Sydney 2 Univ. of Sydney and AAO There is a rich diversity of galaxy properties and we are starting to understand some of the drivers for differences between galaxies. Much progress has been has been made in the last decade, thanks in large part to massively multiplexed surveys using single fibres, but we still lack a complete picture of how galaxies are built. I will discuss how large-scale integral field surveys can address a number of the outstanding questions in the field, starting with the current SAMI Galaxy Survey, and then looking towards the Hector instrument that will carry out integral field surveys of order 50, ,000 galaxies. With SAMI we can start to address how mass and environment influence galaxy structure and history, and I will discuss examples such as the environmental quenching of star formation and the distribution of angular momentum. With larger samples afforded by Hector we can go beyond simply mass and environment, to separate galaxies based on their merger or accretion history, as well as their larger-scale environment. [ 초 IT-02] LIGO-India: Beyond discovery of Gravitational waves. Tarun Souradeep Inter-University Centre for Astronomy and Astrophysics The historic discovery of gravitational waves through direct detection by the LIGO observatories in the USA, in principle, opens up a new window for astronomy. In practice, however, the true launch of gravitational-wave astronomy will await the global array of LIGO like observatories including the planned LIGO-India observatory recently flagged off by the Union cabinet of India. I will review the momentous discovery, the potential of gravitational-wave astronomy and the promise of LIGO-India. [ 초 IT-03] The realm of the ultra-low surface brightness universe David Valls-Gabaud CNRS, Observatoire de Paris; Churchill College, University of Cambridge One of the major discoveries in extragalactic astrophysics made over the past few years is the detection of ultra-diffuse galaxies, a new type of galaxies which appear to be far more numerous than normal galaxies, and which are giants in terms of size, yet dwarfs in terms of luminosity. These galaxies point to the huge discovery potential of the last niche that remains to be explored in observational parameter space: the sky at extremelylow surface brightness. Implications for objects in the Solar System, stellar physics, the interstellar medium, galaxies and cosmology will be addressed, along with the major challenges for pushing the frontiers in ground- and space-based observations. [ 초 IT-04] bservational Evidence for the Coevolution between Supermassive Black Holes and Host Galaxies Minjin Kim 1,2 1 Korea Astronomy and Space science Institute 2 University of Science and Technology (1) The correlation between the mass of supermassive black holes (SMBHs) and the properties of their host galaxies suggests that SMBHs and host galaxies are closely linked in their formation and evolution. While the exact origin of their relationship is still under debate, theoretical models often invoke feedback from active galactic nuclei as a crucial mechanism for establishing the BH-host correlation. In the first part of my talk, I will present possible observational biases in the BH-host relation, and methods to overcome these biases. I will also report our efforts to find observational sign of the AGN feedback in high-z young luminous AGNs. (2) While intermediate-mass black hole (IMBH) is thought be cosmologically important class to understand the link between stellar mass black holes and SMBHs, it is extremely rare in the present-day Universe. In the second part of this talk, I will report a Gemini/GMOS-N IFU study of an ultraluminous X-ray source in NGC 5252, which is a possible candidate of an off-nuclear non-stellar black hole. 한국천문학회보제 42 권 1 호, 2017 년 4 월 / 27

The observed objects are luminous AGNs with the [O III] luminosity > erg/s, and exhibit strong outflow signatures in the [O III] kinematics. We obtain the maps of the narrow and broad components of [O III] and Hα lines by decomposing the emission-line profile. The broad components in both [O III] and Hα represent the non-gravitational kinematics, (i.e., gas outflows), while the narrow components represent the gravitational kinematics (i.e., rotational disks), especially in Hα. By using the spatially integrated spectra within the flux-weighted size of the narrow-line region, we estimate the outflow energetics. The ionized gas mass is ( ) 10 5 M, and the mean mass outflow rate is 4.6±4.3 M /yr, which is a factor of 260 higher than the mean mass accretion rate 0.02±0.01 M /yr. The mean energy injection rate is 0.8±0.6% of the AGN bolometric luminosity Lbol, while the mean momentum flux is (5.4±3.6) L bol /c, except for two most kinematically energetic AGNs. The estimated energetics are consistent with the expectations for energy-conserving outflows from AGNs, yet we do not find any supporting evidence of instantaneous star-formation quenching due to the outflows. [ 구 GC-02] Star Formation of Merging Disk Galaxies with AGN Feedback Effects Jongwon Park, Rory Smith, and Sukyoung K. Yi. Department of Astronomy, Yonsei University Using numerical hydrodynamics code RAMSES, we perform idealized galaxy merger simulations and study the star formation of merging disk galaxies. In our simulations, we consider the active galactic nucleus (AGN) feedback effect. In order to investigate the star formation influenced by AGN, we run ~60 simulations with various initial conditions. We confirm that star formation is more efficiently suppressed in merging galaxies than in isolated galaxies. In the mergers, AGN effect is more significant when the masses of two galaxies are similar. Furthermore, we find that bulge fraction does not affect the star formation when the AGN effect is considered. We discuss the implications on semi-analytic galaxy formation models and the limitation of the current AGN prescriptions.

Multi-frequency VLBI observations were conducted in 29 sessions from January 16, 2013 to March 1, The source was detected and imaged in all available frequency bands. For all observed epochs, the source is compact on the milliarcsecond (mas) scale, yielding a compact VLBI core dominating the synchrotron emission on the mas scale. Based on the multi-wavelength data at 15 and 230 GHz, we found that the source shows multiple prominent enhancements of the flux density at the centimeter (cm) and millimeter (mm) wavelengths, with mm enhancements leading cm enhancements with a time lag of 18±5 days. Turnover frequency is found to vary over our observations between 22 to 69GHz. Taking into account the synchrotron self-absorption model of the relativistic jet in S , we estimated the magnetic field strength in the mas emission region to be mg during the observing period, finding that the magnetic field strength is strongly correlated with the turnover frequency and the 28 / Bull.

[ 박 C-04] A Study of Globular Cluster Systems in the Coma, Fornax, and Virgo Clusters of Galaxies from HST ACS and WFC3/IR Imaging Hyejeon Cho Center for Galaxy Evolution Research & Department of Astronomy, Yonsei University I present new near-infrared (NIR) photometry of globular cluster (GC) systems associated to a cd galaxy NGC 4874 in the core of the Coma cluster and 16 early-type galaxies in the Fornax and Virgo clusters of galaxies using the Infrared Channel of the Wide Field Camera 3 (WFC3/IR) on board the Hubble Space Telescope (HST). Combining these high-resolution NIR data with new HST Advanced Camera for Surveys (ACS) optical photometry for NGC 4874 and existing ACS GC catalogs from the ACS Fornax and Virgo Cluster Surveys, I have examined for the first time the GC systems in a statistically significant optical/nir sample of galaxies spanning a wide range of luminosities and colors. A primary goal of this study is to explore empirically whether the distributions of purely optical and hybrid optical-nir color indices for extragalactic GCs have different forms and whether the relations between these color indices are nonlinear, indicating that they behave differently with underlying metallicity. I find that some GC systems of large galaxies in our sample show color bimodalities that differ between the optical and optical-nir colors, in the sense that they have disparate ratios of blue and red peak GCs, as well as differing ratios in their color dispersions. Consistent with these results, I find empirically that the dependence of hybrid optical-nir color on purely optical color is nonlinear, with an inflection at intermediate metallicities. These findings underscore the importance of understanding the nature of galaxy-to-galaxy variations in the GC color distributions and color color relations, as well as the exact forms of the color metallicity transformations, in interpreting the observational data on GC color bimodality. Our ACS data for NGC 4874 shows that its GC system exhibits a very strong blue tilt, implying a very steep mass metallicity scaling, and the centroid of this GC system is offset by 4±1 kpc from the luminosity center of NGC 4874, in the direction of NGC Finally, I discuss the asymmetrical GC distribution around a dwarf elliptical galaxy in Coma that has a very high relative velocity with respect to the cluster mean at small clustercentric radius.

[ 구 GC-06] Constraints on the Evolution of the Galaxy Stellar Mass Function I: Role of Star Formation, Mergers and Stellar Stripping Emanuele Contini Yonsei University. We study the connection between the observed star formation rate-stellar mass (SFR-M) relation and the evolution of the stellar mass function (SMF) by means of a Subhalo Abundance Matching technique coupled to merger trees extracted from a N-body simulation. Our approach, which considers both galaxy mergers and stellar stripping, is to force the model to match the observed SMF at redshift z>2, and let it evolve down to the present time according to the observed (SFR-M) relation. In this study, we use two different sets of SMFs and two SFR-M relations: a simple power law and a relation with a mass-dependent slope. Our analysis shows that the evolution of the SMF is more consistent with a SFR-M relation with [ 구 GC-07] The mass of the high-z (z~1.132) massive galaxy cluster, SPT-CL J using weak-lensing analysis with HST 한국천문학회보제 42 권 1 호, 2017 년 4 월 / 29

31 2017 봄학술대회 observations Jinhyub Kim 1, Myungkook James Jee 1, and Jongwan Ko 2 1 Department of Astronomy, Yonsei University, 2 Korea Astronomy and Space Science Institute We present a weak-lensing study of the galaxy cluster SPT-CL J at z=1.132 discovered in the South Pole Telescope Sunyaev-Zel dovich (SPT-SZ) survey. The cluster is claimed to be the most massive system at z > 1 in the SPT-SZ survey. The inferred mass (M 200c = (1.27 ± 0.21) M sun ) is somewhat unusual at such a high redshift given the current ΛCDM prediction. The mass estimates, however, may be biased because the hydrostatic assumption may not hold when the universe was about 40% of the current age. In this work, we reconstruct the dark matter distribution and measure the mass of this interesting cluster using weak-lensing analysis based on the images from the Advanced Camera for Surveys and Wide Field Camera 3 on-board the Hubble Space Telescope. We find that the mass distribution of the cluster is unimodal with no significant substructures. The centroid of the dark matter agrees with both galaxy luminosity and number density distributions, as well as the hot gas centroid. We confirm that the cluster is indeed extremely massive (M 200c = (1.81 ± 0.47) M sun ) supporting the previous non-lensing measurements. We also discuss the rarity of the cluster in the ΛCDM cosmology, comparing with the expected abundance of similarly massive clusters. [ 박 GC-08] KYDISC program: The Impact of Mergers on the Evolution of Galaxies Sree Oh Yonsei University In the hope to detect low-surface brightness features (μ r 27 mag arcsec 2 ), we carried out KASI-Yonsei Deep Imaging Survey for Clusters (KYDISC) targeting 14 local clusters at < z < using Magellan/IMACS telescope and CFHT/MegaCam. Out of 1450 cluster galaxies, 18% of galaxies show the signatures of galaxy mergers. We explore merger-driven changes from various point-of-view. We first examine color-magnitude relations, and find that galaxies related to recent mergers are populated more on blue color than their counterparts. Besides, we find the extremely low frequency of mergers on low-mass red-sequence galaxies, suggesting a migration of red galaxies into the green-valley region through merger-driven star-formation. We also study the mass-size relation of our sample, finding a larger galaxy size in galaxies related to recent mergers. Our results suggest that mergers can simultaneously change properties of galaxies, making outliers on galactic scaling relations. [ 구 GC-09] Environmental effects in the stellar populations of Compact Elliptical galaxies Suk Kim, Hyunjin Jeong, Youngdae Lee, Seok-Joo Joo, Jaehyun Lee, Eon-Chang Sung Korea Astronomy & Space Science institute, 776 Daedeokdae-ro, Daejeon , Korea Compact elliptical (ce) galaxies are in a rare class of stellar systems characterized by high stellar densities, small sizes, high velocity dispersion, and high metallicity corresponding to elliptical galaxies. ce galaxies have been observed around massive galaxies, so they could be formed under strong influences of tidal stripping and truncation. However, the recent discovery of isolated ce galaxies requires the need of new formation scenarios. We aim at finding ce galaxies in various environments using SDSS DR12, and studying stellar population of ces as function of environments. Based on the typical properties of ce galaxies, we selected ce candidates by restricting that low-luminosity Mg > 19.5 mag, small sizes Re < 700 pc, and high velocity dispersions σ > 60 km s -1. Since effect radii of ce candidates are mostly smaller than the seeing size of SDSS photometry, we calculated the effective radius by fitting a Sersic profile. In addition, we assumed that host galaxies have brightness with Mr < -21 mag, and an environmental parameter is computed as distances between ce galaxies and host-galaxies. We found 112 ce galaxies at z < 0.05, which have high sersic indices (mean value is 5.2) similar to the typical massive elliptical galaxies. Mgb values of ce galaxies increase as the distances from the host galaxies decrease. Especially, for ces close to the host galaxies (NcE; D host < 300 pc), the Mgb values are similar to those of massive elliptical galaxies, which is consistent with the previous studies. On the other hand, ce galaxies distant from the host galaxies (DcE; Dhost >300 pc) have lower Mgb values than the conventional ce. The Mgb values follow the σ-mgb relation of elliptical galaxies, and are connected to its faint end. This can be explained as a result of different merger histories for differing 30 / Bull. Kor.

For example, NcE galaxies are formed by tidal stripping by massive galaxies as suggested by previous studies, but DcE galaxies could be linked with high-redshift spheroids (e.g. red nuggets) which have not evolved into present-day elliptical galaxies because of the environmental influences. [ 초 GC-10] Long lived spiral structures in galaxies Kanak Saha IUCAA, India Spiral structure in disk galaxies is modeled with ncollisionless N-body simulations including live disks, halos, and bulges with a range of masses. Two of these simulations make long-lasting and strong two-arm spiral wave modes that last for about 5 Gyr with constant pattern speed. These two had a light stellar disk and the largest values of the Toomre Q parameter in the inner region at the time the spirals formed, suggesting the presence of a Q-barrier to wave propagation resulting from the bulge. The relative bulge mass in these cases is about 10%. Models with weak two-arm spirals had pattern speeds that followed the radial dependence of the Inner Lindblad Resonance. In addition to these, we also report a few more cases where two-armed spirals are developed and are maintained for a several rotation time scales. [ 구 GC-11] Gas structures and star formation in the central region of barred-spiral galaxies in self-consistent 3D simulations Woo-Young Seo and Woong-Tae Kim Seoul National University The central regions of barred-spiral galaxies contain interesting gaseous structures such as dust lanes and nuclear rings with intense star formation. While our previous studies were useful in understanding the formation of these structures star formation history, they were limited to 2D isothermal galaxies in which the stellar disk and halo are modeled by fixed gravitational potentials. To study the effects of bar growth as well as the vertical dimension, we use the mesh-free hydrodynamic code named GIZMO and run 3D simulations by treating the stellar disk and halo as being live. We find that the new 3D models form the gaseous features similarly to the previous 2D models, although the detailed formation processes are quite different. For example, a ring has a large radius when it first forms and shrinks over time in the previous 2D models,. In the 3D live-potential models, however, a ring forms small and grows in size with time. We present the results of the new simulations and discuss them in comparison with the previous 2D results.

Numerical simulations predicted that as a barred galaxy evolves, the bar becomes longer by capturing its immediate neighbor disk stars. We test the hypothesis by exploring bar lengths and measuring the light deficit around the bar at various redshift. Supplementing already classified barred galaxies in later type disk galaxies (T 2, Sheth et al. 2008), we classify barred galaxies among earlier type disk galaxies (T<2) up to z~0.8 using F814W images from the Cosmic Evolution Survey (COSMOS). We estimate the length of bars analytically for ~400 galaxies, and find that there is a slight decrease in bar length with redshift. We also find that longer bars show more prominent light deficit around the bar and this trend is stronger for nearby galaxies. Our results are consistent with the predictions from numerical simulations, and imply that the bar induced secular evolution is already in place since z~0.8.

The goals of this survey are to obtain the velocity distribution of low dense filaments and their dense cores for the study of their origin of the formation, to understand whether the dense cores form from any radial accretion or inward motions toward dense cores from their surrounding filaments, and to study the chemical differentiation of the filaments and the dense cores. Until Feb. 2017, the real OTF observation time is 460 hours. We have almost completed mapping observation with four molecular lines ( 13 CO 1-0, C 18 O 1-0, N 2 H + 1-0, and HCO + 1-0) on the five regions of molecular clouds (L1251 of Cepheus, Perseus west, Polaris south, BISTRO region of Serpense, California, and Orion B). The maps of a total area of 7.38 deg 2 for both 13 CO and C 18 O lines and 2.19 deg 2 for both N 2 H + and HCO + lines were obtained. All OTF data were regridded to a cell size of 22 by 22 arcseconds. The 13 CO and C 18 O data show the RMS noise level of about 0.22 K and N 2 H + and HCO + data show about 0.14 K at the velocity resolution of 0.06 km/s. Additional observations will be made on some regions that have not reached the noise level for analysis. We are refining the process for a massive amount of data and the data reduction and analysis are underway.

The prestellar cores provide information of the physical characteristics at the very early stages of star formation. The low dust temperature (<14K) of Planck cold clumps/cores (PGCCs) make them likely to be prestellar objects or at the very initial stage of protostellar collapse. We have been conducting the legacy surveys of Planck cold clumps with the JCMT, the TRAO 14-m and many other telescopes. We aim to study of the initial conditions of star formation and chemical evolutions of the cores in the different environments. From JCMT SCUBA μm survey (SCOPE), we have already identified hundreds of dense cores, which may be at the earliest phase of star formation. Therefore in order to explore the chemical evolution of these dense cores, we used KVN telescopes in order to observe 75 well selected SCUBA-2 cores in many molecules as the follow-up project of KVN Pilot Observation of SCUBA-2. These observations will help advance our understanding of the propoerties of these SCUBA-2 cores in PGCCs.

The cloud s motion is analysed to be moving at about 2.6 km s -1, and is calculated to transverse the Orion Nebula ~2 pc above from the nebula center, toward the direction of about 60 to the line of sight. This cloud had undergone a tidal splitting about a million years ago and had formed a very thin and long cylindrical core well before being engaged in the collision. General implications of this phenomenon are discussed in relation to star formation mechanisms in the GMC.

In particular, turbulence largely determines the density and velocity fields, and can affect the gas kinetic temperature as it decays via shocks. However, despite its central role in star formation and many years of study, the properties of turbulence remain poorly understood. As a part of the TRAO key science program, Mapping turbulent properties of star-forming molecular clouds down to the sonic scale (PI: Jeong-Eun Lee), we mapped the northern region of the Orion A molecular cloud and the L1688 region of the ρ Ophiuchus molecular cloud in 2 sets of lines (13CO 1-0/C18O 1-0 and HCN 1-0/and HCO+ 1-0) using the Taeduk Radio Astronomy Observatory (TRAO) 14-m telescope.

[ 구 IM-05] Escape of Lyβfrom Hot and Optically Thick Media Seok-Jun Chang and Hee-Won Lee Sejong University Symbiotic stars and quasars show strong far UV resonance doublets including O VI 1032 and 1038, which are known to be major coolants of astrophysical plasma with high temperature T > 10 5 K. We investigate the transfer of Hα and Lyβ in an emission nebula of temperature T ~ 10 5, where n=2 population is significant. Line photons of Hα and Lyβ are transferred in the medium through spatial and frequency diffusion altering their identity according to the branching ratios. We adopt a Monte Carlo technique to describe the transfer of Hα and Lyβ in an emission nebula with a uniform density and a simple geometrical figure. We find that the temperature of the emission nebula is the major controlling parameter to produce a nonnegligible flux of Lyβ. In particular, when T exceeds 10 5 K the number flux ratio may reach ~ 25% with line center optical depth of a few. We discuss the formation of broad Hα wings from Raman scattering of Lyβ emergent from a hot emission nebula.

Unlike other astronomical messengers neutrinos can cover all energy range of astronomical phenomena due to their weak interactions and neutrality. Multi messenger astronomy including optical, neutrino, and cosmic ray observations, provides more information on astronomical phenomena and thus such collaborational works are ongoing worldwide. A future Korean neutrino telescope consisting of huge (260 kiloton) water Cherenkov detector under a mountain was proposed in 2016 and the sensitivity studies on various topics are in progress with international collaborators.

The general relativistic modifications should be found applicable to many well-known issues in pulsar astronomy. Among other things, the modifications of Goldreich-Julian model and subpulse drift would be of significant interest and challenging issues. The electromagnetic fields in the pulsar magnetosphere are computed by solving Maxwell's equations defined in the strongly curved spacetime around the pulsar, hence containing the properties of strong gravitational effects. On top of these effects, we also investigate the effects from rotation and obliqueness of the pulsar to work out the general relativistic versions of Goldreich-Julian model and subpulse drift.

The parabolic approximation which assumes that the gravitational radiation from a weakly hyperbolic orbit is the same as that from the parabolic orbit is adopted. Using the radiated energies from the parabolic orbit simulations, we have obtained the impact parameters (b) of the gravitational radiation captures for weakly hyperbolic orbits with respect to the initial energy. The most energetic encounters occur around the boundary between the direct merging and the fly-by orbits, and we find that several percent of the total ADM initial energy can be emitted at the peak. The equal mass BHs emit more energies than unequal mass BHs at the same initial orbital angular momentum in the case of the fly-by orbits. The impact parameters obtained with numerical relativity deviate from those in Post-Newtonian when the encounter is very strong (b 100M), and the deviations are more conspicuous at the high mass ratio. [ 구 HA-05] Search for broadband extended gravitational-wave emission bursts in LIGO S6 in Hz by GPU acceleration Maurice H.P.M. van Putten Yeongsil-Gwan, Room 614, Physics and Astronomy, Sejong University, Seoul, South Korea We present a novel GPU accelerated search algorithm for broadband extended gravitational-wave emission (BEGE) with better than real-time analyis of H1-L1 LIGO S6 data. It performs matched filtering with over 8 million one-second duration chirps. Parseval s Theorem is used to predict the standard deviation σ of filter output, taking advantage of near-gaussian LIGO (H1,L1)-data in the high frequency range of Hz. A multiple of σ serves as a threshold to filter output back to the central processing unit. This algorithm attains 80% efficiency, normalized to the Fast Fourier Transform (FFT). We apply it to a blind, all-sky search for BEGE in LIGO data, such as may be produced by long gamma-ray bursts and superluminous supernovae.

We examine the combined effects of photoionization and radiation pressure for a wide range of cloud masses (10^4-10^6 Msun) and radii (2-80 pc). In all simulations, stars form in densest regions of filaments until feedback becomes strong enough to clear the remaining gas out of the system. We find that the SFE is primarily a function of the initial cloud surface density, Sigma, (SFE increasing from ~7% to ~50% as Sigma increases from ~30 Msun/pc^2 to ~10^3 Msun/pc^2), with weak dependence on the initial cloud mass. Control runs with the same initial conditions but without either radiation pressure or photoionization show that photoionization is the dominant feedback mechanism for clouds typical in normal disk galaxies, while they are equally important for more dense, compact clouds. For low-sigma clouds, more than 80% of the initial cloud mass is lost by photoevaporation flows off the surface of dense clumps. The cloud becomes unbound within ~ initial free-fall times after the first star-formation event, implying that cloud dispersal is rapid once massive star formation takes place. We briefly discuss implications and limitations of our work in relation to observations.

The outflow associated with the radio continuum source VLA 3B is detected in both H2 and [Fe II] emission, while the outflows driven by MM 1, VLA 2 sources were only detected in H 2, indicating the different physical conditions of outflows. We confirm the axis of VLA 3B jet, the position angle of ~ 240. We firstly identified the redshifted, near-ir H2 outflow associated with VLA 2, which is coincident with the previous detections of H 2 O masers.

However, the rate at which a star gains most of its mass and the physics that drives the main phase of stellar growth is still unclear. The typical luminosity of observed protostars is smaller than what expected from the Shu s inside-out collapse model, which predicts a constant mass accretion rate. The episodic accretion model has been suggested as a solution of this luminosity problem. The JCMT Transient survey is a long term monitoring program using JCMT/SCUBA-2 to detect accretion variability of protostars in the eight nearby star-forming regions. Recently, we found a rise of the 850 micron flux at a clump in the Serpens main region at the rate of ~17% relative to the mean flux over previous observations. The submm clump is associated with a class I protostar, EC53, which has been reported as a binary system with a periodic variability. In this talk, we will provide a brief overview of the JCMT Transient Survey project, present the detection of the variable source, and discuss about follow-up observations.

The main science goals of the mission include investigations of the galaxy formation, cosmic web, and the cosmic background radiation in the NUV-NIR regions. In this paper, we present the science cases and several technical challenges to be resolved along with the future milestones for the success of the KST mission.

To achieve the major scientific objectives for the study of the cosmic star formation in local and distant universe, the spectro-photometric survey covering more than 100 square degree will be performed. The main observational targets will be nearby galaxies, galaxy clusters, star-forming regions and low background regions. The off-axis optics was developed to cover a wide field of view (2 deg. x 2 deg.) as well as the wide wavelength range from 0.95 to 2.5μm, which were revised based upon the recent test and evaluation of the NISS instrument. The mechanical structure were tested under the launching condition as well as the space environment. The signal processing from infrared sensor and the communication with the satellite were evaluated after the integration into the satellite. The flight model of the NSS was assembled and integrated into the satellite. To verify operations of the satellite in space, the space environment tests such as the vibration, shock and thermal-vacuum test were performed. The accurate calibration data were obtained in our test facilities. Here, we report the test results of the flight model of the NISS.

[ 구 ST-04] Small scale magnetospheric and Ionospheric Plasma Experiments; SNIPE mission Junga Hwang, Jaejin Lee, Jongdae Shon, Jaeheung 40 / Bull. Kor. Astron. Soc. Vol. 42 No.1, Apr. 2017

42 구두발표초록 Park, Young-Sil Kwak, Uk-Won Nam, and Won-Kee Park Korea Astronomy and Space Science Institute The observation of particles and waves using a single satellite inherently suffers from space-time ambiguity. Recently, such ambiguity has often been resolved by multi-satellite observations; however, the inter-satellite distances were generally larger than 100 km. Hence, the ambiguity could be resolved only for large-scale (> 100 km) structures while numerous microscale phenomena have been observed at low altitude satellite orbits. In order to resolve those spatial and temporal variations of the microscale plasma structures on the topside ionosphere, SNIPE mission consisted of four (TBD) nanosatellites (~10 kg) will be launched into a polar orbit at an altitude of 700 km (TBD). Two pairs of satellites will be deployed on orbit and the distances between each satellite will be from 10 to 100 km controlled by a formation flying algorithm. The SNIPE mission is equipped with scientific payloads which can measure the following geophysical parameters: density/temperature of cold ionospheric electrons, energetic (~100 kev) electron flux, and magnetic field vectors. All the payloads will have high temporal resolution (~ 16 Hz (TBD)). This mission is planned to launch in The SNIPE mission aims to elucidate microscale (100 m-10 km) structures in the topside ionosphere (below altitude of 1,000 km), especially the fine-scale morphology of high-energy electron precipitation, cold plasma density/temperature, field-aligned currents, and electromagnetic waves. Hence, the mission will observe microscale structures of the following phenomena in geospace: high-latitude irregularities, such as polar-cap patches; field-aligned currents in the auroral oval; electro-magnetic ion cyclotron (EMIC) waves; hundreds kev electrons precipitations, such as electron microbursts; subauroral plasma density troughs; and low-latitude plasma irregularities, such as ionospheric blobs and bubbles. We have developed a 6U nanosatellite bus system as the basic platform for the SNIPE mission. Three basic plasma instruments shall be installed on all of each spacecraft, Particle Detector (PD), Langmuir Probe (LP), and Scientific MAGnetometer (SMAG). In addition we now discuss with NASA and JAXA to collaborate with the other payload opportunities into SNIPE mission. [ 구 ST-05] Different Responses of Solar Wind and Geomagnetism to Solar Activity during Quiet and Active Periods Roksoon Kim 1,2, Jongyeob Park 1,3, Jihye Baek 1, Bogyeung Kim 4 1 Korea Astronomy and Space Science Institute, 2 University of Science and Technology, 3 Kyung Hee University, 4 Chungnam National University It is well known that there are good relations of coronal hole (CH) parameters such as the size, location, and magnetic field strength to the solar wind conditions and the geomagnetic storms. Especially in the minimum phase of solar cycle, CHs in mid- or low-latitude are one of major drivers for geomagnetic storms, since they form corotating interaction regions (CIRs). By adopting the method of Vrsnak et al. (2007), the Space Weather Research Center (SWRC) in Korea Astronomy and Space Science Institute (KASI) has done daily forecast of solar wind speed and Dst index from Through years of experience, we realize that the geomagnetic storms caused by CHs have different characteristics from those by CMEs. Thus, we statistically analyze the characteristics and causality of the geomagnetic storms by the CHs rather than the CMEs with dataset obtained during the solar activity was very low. For this, we examine the CH properties, solar wind parameters as well as geomagnetic storm indices. As the first result, we show the different trends of the solar wind parameters and geomagnetic indices depending on the degree of solar activity represented by CH (quiet) or sunspot number (SSN) in the active region (active) and then we evaluate our forecasts using CH information and suggest several ideas to improve forecasting capability.

In this study, we calculate models with mass range of 9-39M_sun and several different convection parameters (e.g. mixing length, overshooting, and semiconvection) at SMC, LMC, Milky Way, and M31 metallicities. We compare the calculated evolutionary tracks with observed RSGs in SMC, LMC, Milky Way and M31, and discuss appropriate input physical parameters in model calculation. We find that a larger mixing length parameter is necessary for M31 metallicity to fit the positions of RSGs in H-R diagram, compared to lower metallicity environments. Theoretically predicted numbers of yellow supergiant stars (YSGs) are also compared with the observed population. We find that Ledoux models with semiconvection can better explain the number of YSGs. Finally, we investigate the final radius, final star mass, and final hydrogen envelope mass of RSGs and discussed the their properties as type II-P supernova progenitors. [ 구 SH-02] The CN-CH positive correlation in the globular cluster NGC 5286 Dongwook Lim, Seungsoo Hong, Young-Wook Lee Center for Galaxy Evolution Research & Department of Astronomy, Yonsei University We performed low-resolution spectroscopy for the red giant stars in the Galactic globular cluster (GC) NGC 5286, which is known to show intrinsic heavy element variations. We found that these stars are clearly divided into two subpopulations by CN index. These two subpopulations also show significant differences in the HK and CH indices, where the CN-strong stars are more enhanced in both indices. From the comparison with high-resolution spectroscopic data of Marino et al. (2015), we found that the CN- and HK -strong stars are also increased in the abundances of s-process elements and Fe. It appears that, therefore, these stars are later generation stars probably affected by supernova enrichment. In addition, NGC 5286 shows the CN-CH positive correlation among the whole sample, which is only discovered in the GCs with heavy element variations such as M22 and NGC Therefore, these results strengthen our previous suggestion that the CN-CH positive correlation may be associated with the heavy element variations in the GCs. [ 구 SH-03] Origin of Low-mass Hypervelocity Stars in the Galactic Disk Bum-Suk Yeom, Young Sun Lee, Youngkwang Kim, Doo-Ri Han Department of Astronomy and Space Science, Chungnam National University, Daejeon 34134, Korea, cometyeom@cnu.ac.kr We present the analysis of chemical abundances and kinematics for six hypervelocity star (HVS) candidates. These objects are G/K-type low-mass stars in the Galactic disk, while other HVSs previously found are B-type high-mass objects in the Galactic halo. The stellar orbits and kinematics of our HVS candidates suggest that they do not originate in the Galactic center or in an accretion event, indicative of yet-unknown mechanisms that produce kinematically-extreme disk stars. In order to study in detail their origin, we obtained medium-resolution (R~6000) spectra of these stars and derived abundances of several chemical elements (Mg, Ca, Si, Ti, Cr, Fe, and Ni). From the comparison of the chemical abundances with the Galactic stellar components (disk, bulge, halo, and dwarf galaxies) and the kinematic properties of our HVSs, we conclude that two of them are likely ejected from the Galactic disk, one originated from the Galactic center as for the young B-type HVSs, and the other one might be ejected from either the Galactic disk or other regions.

These two target stars are important because HD is the largest star and HD is the brightest star for exoplantary system candidate so we can understarnd how evolved stars affect planets by researching these stars. We calculated precise RV measurements of 38 and 24 spectra from November 2010 to January 2017 and June 2010 to January 2017, respectively. We dreived the RV variation period for days of HD 18438, days for HD We conclude that the RV variation of HD is caused by planetary companion which has the mass of 14.7 MJup, semi-major axis of 2.2 AU, and eccentricity of 0.27 assuming the stellar mass of 2.34 M. On the other hand, the origin of RV variation of HD with period of days is still uncertain. It might be caused by stellar chromospheric activity or planetary companion, so more observations and tests are required.

Comparing with previous studies which usually considered single BH masses, our models consist of two-component BH masses, or continuous BH mass function with single mass ordinary cluster stars. During the early stage of dynamical evolution, initially distributed BHs are move to the cluster center by dynamical friction, then BH-BH binaries start to be formed, and eventually be ejected from the cluster due to three body interaction. Finally we find the formation efficiency of high mass BHs are alwats larger than that of lower mass BHs, implying that a BH mass spectrum expected from GW observation should be biased to high mass. In addition, mass ratios of BHs in binaries prefer similar masses (ratio~1), while the most extreme case is less than 3. Expected merger rate from our models is about 7 BH-BH mergers per Mpc 3 per yr.

The Spitzer data exhibit finite-source effects due to the passage of the lens close to or directly over the surface of the source star as seen from Spitzer. Thanks to measurements of the microns parallax and the finite-source effect, we find that the lens of OGLE-2015-BLG-1482 is a very low-mass star with the mass 0.10±0.02 M or a brown dwarf with the mass 55±9 MJ, which are respectively located at DLS = 0.80±0.19 kpc and DLS = 0.54±0.08 kpc, and thus it is the first isolated low-mass microlens that has been located in the Galactic bulge. The degeneracy between the two solutions is severe. The fundamental reason for the degeneracy is that the finite-source effect is seen only in a single data point from Spitzer and this single data point gives rise to two ρ solutions.

However, only six systems have been found to be a doubly eclipsing quadruple, which consists of two eclipsing binaries, and four systems to be a triply eclipsing hierarchical triple. Recently, the 15 doubly eclipsing multiple candidates located in the Large Magellanic Cloud (LMC) have been reported by the OGLE project. In order to examine whether these candidates are real multiple systems with eclipsing features, we performed a high-cadence time-series photometry for the LMC using the KMTNet (Korea Microlensing Telescope Network) 1.6 m telescopes in three site (CTIO, SAAO, and SSO) during The KMTNet data will help reveal the photometric properties of the multiple-star candidates.

To understand the properties and physical mechanism of variability, we are performing the KMTNet Active Nuclei Variability Survey (KANVaS). Especially, we investigated intra-night variability of AGN with KMTNet data which observed COSMOS field during 3 separate nights from 2015 to 2016 in B, V, R, and I bands. Each night was composed of 5, 9, and 11 epochs with min cadence. To find AGN in the COSMOS field, we applied multi-wavelength selection methods. Using X-ray, mid-infrared, and radio selection methods, 50-60, , number of AGN are detected, respectively. Achieving photometric uncertainty ~0.01mag by differential photometry, we employed a standard time-series analysis tool to identify variable AGN, chi-square test. Preliminary results indicate that there is no evidence of intra-night optical variability of AGN. It is possible that previous studies discovered intra-night variability used inappropriate photometric error. However, main reason seems that our targets have fainter magnitude (higher photometric error) than that of previous studies. To discover variability of AGN, we will investigate longer timescale variability of AGN.

The source is entering a significantly active phase with long-term increase in radio flux at cm wavelengths since 2005, and the increased activity at very-high-energy (VHE) gamma rays. In order to study properties of sub-pc-scale structure and the circumnuclear environment in 3C 84, we have conducted multi-epoch VLBI observations with the Korean VLBI Network (KVN) at 86 and 129 GHz, and monthly monitoring by the KVN and VERA Array (KaVA) at 43 GHz from 2015 August.

In previous works it has been shown that non-dispersive (e.g. tropospheric) effects can be calibrated with the frequency phase transfer (FPT) technique. The coherence time can thus be significantly extended. Ionospheric effects, which can still be significant, remain however uncalibrated after FPT, as well as the instrumental effects. In this work, we implement a further phase transfer between two FPT residuals (i.e. so-called FPT2) to calibrate the ionospheric effects based on their frequency dependence. We show that after FPT2, the coherence time at 3 mm can be further extended beyond 8 hours, and the residual phase errors can be sufficiently canceled by applying the calibration of another source, which can have a large angular separation from the target (> 20 ). Calibrations for all-sky distributed sources with a few calibrators are also possible after FPT2. One of the strengths and uniqueness of this calibration strategy is the suitability for high frequency all-sky survey observations including very weak sources. We discuss the introduction of a pulse calibration system in the future to calibrate the remaining instrumental effects and allowing the possibility of imaging the source structure at high frequencies with FPT2, where all phases are fully calibrated without involving any sources other than the target itself.

Unlike GCs, RR Lyrae stars in the Local Group dwarf galaxies show Oosterhoff-intermediate characteristics. The origin of this, however, is yet to be understood.

[ 포 GC-03] On the origin of Na-O anticorrelation in globular clusters Jaeyeon Kim and Young-Wook Lee Center for Galaxy Evolution Research & Department of Astronomy. Yonsei University In order to investigate the origin of multiple stellar populations in the halo and bulge of the Milky Way, we have constructed chemical evolution models for the low-mass proto-galactic subsystems such as globular clusters (GCs). Unlike previous studies, we assume that supernova blast waves undergo blowout without expelling the pre-enriched gas, while relatively slow winds of massive stars, together with the winds and ejecta from low and intermediate mass asymptotic giant branch stars, are all locally retained in these less massive systems. We first applied these models to investigate the origin of super-helium-rich red clump stars in the metal-rich bulge as recently suggested by Lee et al. (2015). We find that chemical enrichments by the winds of massive stars can naturally reproduce the required helium enhancement (dy/dz = 6) for the second generation stars. Disruption of these building blocks in a hierarchical merging paradigm would have provided helium enhanced stars to the bulge field. Interestingly, we also find that the observed Na-O anticorrelation in metal-poor GCs can be reproduced, when multiple episodes of starbursts are allowed to continue in these subsystems. Specific star formation history with decreasing time intervals between the stellar generations, however, is required to obtain this result, as would be expected from the orbital evolution of these subsystems in a proto-galaxy. The mass budget problem is also much alleviated by our models without ad-hoc assumptions on star formation efficiency and initial mass function. [ 포 GC-04] Chemical Properties of Star-Forming Dwarf Galaxies in Different Environments Jiwon Chung 1, Soo-Chang Rey 1, Eon-Chang Sung 2, Woong Lee 1, Suk Kim 2, Yongdae Lee 2 1 Chungam National University, 2 Korea Astronomy and Space Science Institute Star forming dwarf galaxies in various environments are attractive objects for investigating the environmental effects on chemical evolution of dwarf galaxies. Using SDSS DR7 spectroscopic data and GALEX ultraviolet (UV) imaging data, we study the chemical properties of star forming dwarf galaxies in various environments of the Virgo cluster, Ursa Major group, and field. We derived gas-phase abundance, galaxy mass, and UV specific star formation rate (ssfr) of subsample, early-type (ETD) and late-type star forming dwarf (LTD) galaxies, which are divided by visually classified galaxy morphology. We found no O/H enhancement of LTDs in cluster and group environments compared to the field, implying no environmental dependence of the mass-metallicity relation for LTDs. LTDs in the Virgo cluster and Ursa Major group have similar ssfr at a given galaxy mass, but they exhibit systematically lower ssfr than those in isolated field environment. We suggest that LTDs in the Virgo cluster are an infalling population that was recently accreted from the outside of the cluster. We found that ETDs in the Virgo cluster and Ursa Major group exhibit enhanced O/H compared to those in the field. However, no distinct difference of N/O of galaxies between different environments. The chemically evolved ETDs in the Virgo cluster and Ursa Major group also show similar mass-ssfr relation, but systematically lower ssfr at a fixed galaxy mass compared to the field counterparts. We suggest that ETDs in the Virgo cluster and Ursa Major group have evolved under the similar local environments. We also discuss the evolutionary path of ETDs and LTDs with respect to the environmental effects of ram pressure stripping and galaxy interaction/merging.

However, measuring metallicity is limited to low redshift (z<3.5) due to the faintness of the metallicity indicators in normal galaxies. For high redshift universe, active galactic nuclei (AGN) can be used to constrain the host galaxy metallicity. 한국천문학회보제 42 권 1 호, 2017 년 4 월 / 49

51 2017 봄학술대회 Previous studies investigated AGN metallicity using emission line flux ratios (i.e., NV/CIV and FeII/MgII), finding no evolution up to z~6. Those results might be due to selection effect since previous studies are based on very luminous AGNs. The observed luminosity-metallicity relation of AGNs (e.g., Nagao et al. 2006) suggests that luminous AGNs may be already matured at the observed epoch. Considering the luminosity-metallicty relation, we focused on low luminosity AGNs to find young AGNs (i.e., low metallicity). Through the Gemini/GNIRS observation in 2012A and 2015A (K-GMT GN-2015A-Q-203 PI: Shin, J.), we obtained the Gemini/GNIRS data for 7 high redshift AGNs (3.0<z<3.5). We will present and discuss our preliminary results on the their metallicity. [ 포 GC-06] Do Galaxy Mergers Enhance Star Formation Rate in Nearby Galaxies? Gu Lim( 임구 ), Myungshin Im( 임명신 ), Changsu Choi( 최창수 ), Yongmin Yoon( 윤용민 ) Center for Exploration of the Origin of the Universe (CEOU), Astronomy Program, 1Dept. of Physics & Astronomy, Seoul National University ( 서울대학교 ) We present our study of the correlation between star formation rate(sfr) and merging activities of nearby galaxies(d<150mpc). Our study uses 265 UV-selected galaxies which are not classified as AGN. The UV selection is made using the GALEX Atlas of Galaxies (Gil de Paz+07) and the updated UV catalog of nearby galaxies (Bai+15). We use deep R band optical images reaching to 1 surface brightness detection limit ~27 mag/arcsec 2 to classify merger features by visual inspection. We also estimated unobscured SFR(SFR NUV ) and obscured SFR(SFR W4 ) using Near-UV continuum and 22 micron Mid-IR luminosity respectively as a indicator of star forming activity. The fraction of galaxies with merger features in each SFR bin is obtained to see if how the fraction of galaxies with merging features(f m ) changes as a function of SFR. As a result, for 203 late type galaxies(ltgs), we found that merger fraction increases from ~8% up to 50% with SFR W4, while for 229 LTGs SFR NUV shows relatively consistent fraction(~18%) of merger fraction. For early type galaxies(etgs), we could also find no significant correlation between F m and SFR(both SFR NUV and SFR W4 ). This result suggests that a main driver of star forming activity of UV bright galaxies, especially for obscured late types, is mergers.

Jee Yonsei University The galaxy cluster Abell 115 shows ongoing merger features, which suggest that it might be in an intermediate phase of dynamical evolution. As merging clusters often show, the characteristic hints of A115 s merging activities include radio relics, double X-ray peaks, and large offsets between the cluster member galaxies and the X-ray distributions. To constrain the exact stage of the merger, it is necessary to obtain its dark matter distribution. In this study, we carry out a precision weak lensing study of this interesting system based on Subaru images. We present our mass reconstruction together with descriptions on our core procedure of the analysis: Subaru data reduction, galaxy shape measurement, and source selection. We find that Abell 115 consists of two massive dark matter clumps, which closely follow the cluster galaxies. Our weak lensing mass estimate is a few factors lower than the published dynamical mass obtained from velocity dispersion. This large mass discrepancy may be attributed to a significant departure from dynamical equilibrium. [ 포 GC-10] Where is the Dark Matter in the Double Radio Relic Galaxy Cluster PLCKG ?

Jee 1, William Dawson 4, Nathan Golovich 2, Daniel Gruen 3, Brian Lemaux 2, David Wittman 2 1 Yonsei University, 2 UC Davis, 3 Stanford University, 4 Lawrence Livermore National Lab Diffuse radio relics are often detected in merging galaxy clusters and are emitted by synchrotron process. Radio relics are believed to trace the shock waves in the intracluster medium induced by ram pressure during a major cluster merger. Radio halos and relics are found in approximately 50 galaxy clusters to date that are all in a state of merging. The rarest of these galaxy clusters contain pairs of relics of similar brightness as well as a radio halo. The massive galaxy cluster PLCKG belongs to this rare population and is the second most significant detection from the Planck SZ All-sky Survey. Perhaps even more intriguing is that the radio relics are observed at vastly different distances from the X-ray peak requiring a complex merging scenario. In this study, we use weak-lensing to peer deeper into the merging scenario by reconstructing the dark matter distribution. We relate the mass distribution to the radio, X-ray, and optical emissions to provide constraints for future simulations of the merger. Fitting an NFW profile to the tangential shear we infer the mass of the cluster and discuss its implications for the merging scenario.

These AGNs are selected based on the radioactivity (L1.4GHz erg s-1) as well as optical properties as type 2 AGNs. By using the high spatial resolution of the Red Channel Cross Dispersed Echellette Spectrograph at the Multiple Mirror Telescope, we investigate in detail the [O III] and stellar kinematics. We spatially resolve and probe the central AGN-photoionization sizes, which is important in understanding the structures and evolutions of galaxies. We find that the typical central AGN-photoionization sizes of our targets are in range of kpc. We study the [O III] kinematics along the radio jets to test whether there is a link between gas outflows in the narrow-line region and radio jet emissions. Contrary to our expectation, we find no evidence that the gas outflows are directly connected to radio jet emission.

Specifically, we simulate a Milky Way-like galaxy colliding consecutively with six twice-massive early-type galaxies containing hot diffuse gas on their halos, with various impact parameters ranging from 65 kpc/h to 15 kpc/h at the relative speed of about 1500 km/s. We show that galaxy-galaxy encounters play a significant role in a cluster environment in gas stripping and star formation quenching through hydrodynamic interactions of late-type galaxies with cluster early-type galaxies. [ 포 GC-13] A pilot study on the formation and evolution of the Intracluster light: Preliminary results of the Coma cluster Jaewon Yoo 1,2, Jongwan Ko 1,2 1 Korea Astronomy and Space Science Institute (KASI), 2 University of Science and Technology (UST) Galaxy clusters are the most massive gravitationally bound systems and thus probably the most recent objects to form. One of promising routes to understand the assembly history of galaxy clusters is to measure observable quantities of components in clusters that are sensitive to the evolutionary state of the cluster. Recent deep observations on the nearby clusters show distinct diffuse intracluster light (ICL), that the light from stars are not bound any individual cluster galaxy, however until now this component has not been well studied due to its faint nature, with typical brightness of ~100 times fainter than the sky background. As shown in galaxy cluster simulation studies, the ICL abundance increases during various dynamical exchanges of galaxies such as the disruption of dwarf galaxies, major mergers between galaxies and the tidal stripping of galaxies. Thus, the ICL is an effective tool to measure the evolutionary stage of galaxy clusters. Moreover, the investigation of the ICL evolution mechanism will allow us understand the galaxy evolution process therein. In this pilot study, we target the Coma cluster, where the existing ICL studies are limited only in the central region. With large and uniform deep optical images from the Subaru telescope, available only recently (Okabe et al. 2014), we are developing a robust ICL measurement technique, extracting the ICL surface brightness and color profiles, which will allow us to study the origin of the ICL and its connection to the evolutionary history of the Coma cluster. For the next phase, we plan to utilize the plenty of spectroscopy data from the MMT telescope to compare ICL properties with the star formation history of the brightest cluster galaxies (BCG), and discuss the ICL formation mechanism of the Coma cluster by comparing the distribution of cluster galaxies with the distribution of diffuse light inside the Coma cluster. 우주론 / 암흑물질, 에너지 [ 포 CD-01] Post-reionization Kinetic Sunyaev-Zel dovich Effect in Illustris Simulation Hyunbae Park 1, Cristiano Sabiu 1, Xiao-dong Li 2, Changbom Park 2, Juhan Kim 2 1 Korea Astronomy and Space science Institute, 2 Korea Institute for Advanced Study We develop a methodology to use the redshift dependence of the galaxy 2-point correlation function (2pCF) as a probe of cosmological parameters. The positions of galaxies in comoving Cartesian space varies under different cosmological parameter choices, inducing a redshift-dependent scaling in the galaxy distribution. This geometrical distortion can be observed as a redshift-dependent rescaling in the measured 2pCF. The shape of the 2pCF exhibits a significant redshift evolution when the galaxy sample is analyzed under a cosmology differing from the true, simulated one. Other contributions, including the gravitational growth of structure, galaxy bias, and the redshift space distortions, do not produce large redshift evolution in the shape. We show that one can make use of this geometrical distortion to constrain the values of cosmological parameters governing the expansion history of the universe. This method could be applicable to future large scale structure surveys, especially photometric surveys such as DES, LSST, to derive tight cosmological constraints.

As a part of this project, we have constructed our own SN catalogue. SALT2 and MLCS2k2 light-curve fitters implemented in SNANA package are employed to analyze the light-curve data.

[ 포 CD-03] MMT Spectroscopy of Early-type Host Galaxies of Type Ia Supernovae Yijung Kang, Young-Lo Kim, and Young-Wook Lee Department of Astronomy and Center for Galaxy Evolution Research, Yonsei University, Seoul 03722, Korea The origin of the well-known correlation between Hubble residual of Type Ia Supernova (SN Ia) and mass of their host galaxies is yet to be fully understood. In our first paper of our YOnsei Evolutionary Supernovae Evolutionary Investigation (YONSEI) project, we found a significant (~3.9σ) correlation between host galaxy mass (velocity dispersion) and population age from high S/N host spectra observed using LCO 2.5 m telescope. Since there is no correlation with metallicity, our result suggests that stellar population age is mainly responsible for the relation between host mass and HR. In order to explore this more directly, we have subsequently observed more sample of nearby early-type host galaxies using MMT 6.5 m telescope. In this poster presentation, we will report our progress in this project and show the preliminary results from our MMT observations. function of the SDSS-IV eboss DR14 quasar sample Peter D. Choi 1, Graziano Rossi 1, Zachary Slepian 2, Daniel Eisenstein 3, Shirley Ho 2,4, David Schlegel 2 1 Sejong University, 2 Lawrence Berkeley National Laboratory, 3 Harvard-Smithsonian Center for Astrophysics, 4 Carnegie Mellon University While quasars are sparse in number density, they reside at relatively high-redshift as compared to galaxies. Hence, they are likely to be less non-linearly evolved than the galaxy population, and thus have a distribution that more closely mirrors the primordial density field. Therefore, they offer an intriguing opportunity to search for primordial non-gaussianity (PNG). To this end, the 3-point correlation function (3PCF) is an excellent statistical tool to detect departures from Gaussianity, vanishing for a Gaussian field. In this work, we will make the first-ever measurement of the large-scale quasar 3PCF from the SDSS-IV DR14 quasar sample (spanning the largest volume to-date) to place constraints on PNG through the usual f_nl-type parametrization. This work will use the order N^2-time 3PCF algorithm of Slepian & Eisenstein (2015), with N the number of objects.

This survey covers 7 < l < 62 and b < 1.5, where active interaction of stars and interstellar medium is expected. With median seeing of 0.8 arcsec, 5 sigma detection limit of 18.7 mag and surface brightness limit of W m -2 arcsec -2, this survey gives an opportunity to statistically study Galactic [Fe II] emitting sources for the first time. In order to identify Ionized Fe Objects (IFOs) in survey area systematically, we conducted visual inspection and automatic detection simultaneously. Total of ~300 extended IFOs are identified, most of them are found out to be part of supernova remnants (SNRs), young stellar objects, HII regions and planetary nebulae. The majority of IFOs are new discoveries which reveal shocked structures in high-extinction region. Spatial distribution of IFOs suggest that they trace Galactic structure. As a part of spectroscopic follow-up, we observed SNR candidate IFO J with IGRINS (Immersion Grating Infrared Spectrograph, Yuk+2010), mounted on 2.7m Harlan Smith telescope. This unknown arc-like, 6 -long IFO is coincident with inner part of radio continuum loop G , which has been known as HII region.

Recently, 2MASS J exhibited an outburst and was identified as an FUor. It provides an important opportunity to investigate the whole FUors phenomenon from its pre-outburst to its post-outburst phase. We observed 2MASS J with the Bohyunsan Optical Echelle Spectrograph (BOES) of the Bohyunsan Optical Astronomy Observatory (BOAO) and the Immersion GRating INfrared Spectrograph (IGRINS) of Harlan J. Smith Telescope (HJST) at the McDonald observatory since December 24, We detected a number of lines and present here our analysis for time variations of those spectral lines. [ 포 IM-03] A multi-wavelength study of N63A: A SNR within an H II region in the LMC. Rommy L. S. E. Aliste C., Bon-Chul Koo, Yong-Hyun Lee Seoul National University The nature and physical environments of SNRs are diverse, and for this reason, the understanding of the properties of nearby SNRs is useful in interpreting the emission from SNRs in remote galaxies where we cannot resolve them. In this regard, the LMC is a unique place to study SNRs due to its proximity, location, and composition compared with our galaxy. We carried out a multi-wavelength study of SNR N63A in the LMC, a young remnant of the SN explosion of one of the most massive (> 40 Msun) stars in a cluster. It is currently expanding within a large H II region formed by OB stars in the cluster and engulfing a molecular cloud (MC). As such, N63A is a prototypical SNR showing the impact of SN explosion on the cluster and its environment. Its morphology varies strongly across the wave bands, e.g. the size in X-ray is three 54 / Bull. Kor. Astron. Soc. Vol. 42 No.1, Apr. 2017

However, the bright optical nebula would correspond to a MC swept up by the SNR, and consequently the interaction SNR-MC is limited to the central portion of the SNR. We aimed to study the overall structure of N63A, using near-ir imaging and spectroscopic observations to obtain the physical parameters of the atomic shocks, and also to understand how the SNR- MC interaction works and reveal the structure of the shocked cloud as well as the consequences of the impact of the SNR shock on the MC, comparing information obtained in different wavelengths. [ 포 IM-04] On the claimed X-shaped structure in the Milky Way bulge Daniel Han and Young-Wook Lee Center for Galaxy Evolution Research & Department of Astronomy, Yonsei University A number of recent studies have claimed that the double red clump observed in the Milky Way bulge is a consequence of an X-shaped structure. In particular, Ness & Lang (2016) report a direct detection of a faint X-shaped structure in the bulge from the residual map of the Wide-Field Infrared Survey Explorer (WISE) image. Here we show, however, that their result is seriously affected by a bulge model subtracted from the original image. When a boxy bulge model is subtracted, instead of a simple exponential bulge model as has been done by Ness & Lang, we find that most of the X-shaped structure in the residuals disappears. Furthermore, even if real, the stellar density in the claimed X-shaped structure appears to be too low to be observed as a strong double red clump at [ 포 IM-05] Density-Magnetic Field correlation in MHD turbulence driven by forcing with different correlation time Heesun Yoon 1, Jungyeon Cho 1, and Jongsoo Kim 2,3 1 Department of Astronomy and Space Science, Chungnam National University, 2 Korea Astronomy and Space Science Institute (KASI), 3 Astronomy and Space Science Major, University of Science and Technology (UST) We study the effect of driving scheme on the density-magnetic field correlation. We numerically investigate how the correlation time of driving affects the correlation between density and magnetic field. We performed MHD turbulence simulation using two different driving schemes a finite-correlated driving and a delta-correlated driving. In the former, the forcing vectors change continuously with a correlation time comparable to the large-eddy turnover time. In the latter, the direction and amplitude of driving changes in a very short time scale.

We mapped a square region of 60 arcmin by 60 arcmin in the continuum emission from 0.89 mm to 2.0 mm wavelength using MUSIC mounted on the Caltech Submillimeter Observatory 10.4 m telescope. Eight sources were detected in at least two wavelength bands, and all the detected emission comes from thermal dust continuum radiation of dense cloud cores. Their spectral energy distributions were characterized. The dust emissivity spectral index is beta = 1.3 on average, within the range of typical cores in nearby star-forming regions. Two cores, V380 Ori NE and HH 34 MMS, have unusually low emissivity index of beta = 0.3. These cores may contain millimeter-sized dust grains, which suggests that the lifetime of some dense cores can be much longer than the free-fall timescale.

57 2017 봄학술대회 Complex organic molecules (COMs) are commonly detected in star forming regions and considered important species since they are seeds of prebiotic molecules. Although COMs form in ice mantles on dust grains, they are preferentially detected in the gas phase. The origin of the gaseous COMs highly depends on the circumstance of each star forming region. Therefore, the distribution of COMs emission reflects the physical and chemical conditions of the region. We present the newly detected COMs, especially methanol emission lines toward two massive star forming regions, G and G in the Atacama Large Millimeter/submillimeter Array Band 3 observations during the Cycle 2 phase. Multiple transitions of methanol are detected in both regions but show different emission morphology. The origin of the desorption (e.g. shocks or high energy photons) is discussed. [ 포 IM-08] Statistical study of turbulence from polarized synchrotron emission Hyeseung Lee 1, Chungyeon Cho 1, Alexandre Lazarian 2 1 Chungnam National University 2 University of Wisconsin-Madison When turbulent motions perturb magnetic field lines and produce magnetic fluctuations, the perturbations leave imprints of turbulence statistics on magnetic field. Observation of synchrotron radiation is one of the easiest ways to study turbulent magnetic field. Therefore, we study statistical properties of synchrotron polarization emitted from media with magnetohydrodynamic (MHD) turbulence, using both synthetic and MHD turbulence simulation data. First, we obtain the spatial spectrum and its derivative with respect to wavelength of synchrotron polarization arising from both synchrotron radiation and Faraday rotation. The study of spatial spectrum shows how the spectrum is affected by Faraday rotation and how we can recover the statistics of underlying turbulent magnetic field as well as turbulent density of electrons from interferometric observations that incorporate the effects of noise and finite telescopic beam size. Second, we study quadrupole ratio to quantitatively describe the degree of anisotropy introduced by magnetic field in the presence of MHD turbulence. We consider the case that the synchrotron emission and Faraday rotation are spatially separated, as well as the situation that the sources of the synchrotron radiation and thermal electrons causing Faraday rotation exist in the same region. In this study, we demonstrate that the spectrum and quadrupole ratio of synchrotron polarization can be very informative tools to get detailed information about the statistical properties of MHD turbulence from radio observations of diffuse synchrotron polarization. [ 포 IM-09] Obtaining the driving scale of turbulence from observations Jungyeon Cho ( 조정연 ) Department of Astronomy and Space Science, Chung National University, Daejeon, Korea To maintain turbulence in astrophysical fluids, driving is required. Constraining the driving scale of turbulence is important to identify the driving mechanism and also to obtain more accurate turbulence statistics from observations. We discuss how to obtain the driving scale of turbulence from observations. First, we explain the method to obtain the driving scale from the standard deviation of centroid velocity (i.e. the first moment of the line profile). Second, we discuss other techniques to obtain the driving scale.

The telescope comprises two pieces of aluminum-alloy freeform mirrors that are fabricated with diamond turning machine (DTM) process. We designed optomechanical structures where optical components in the telescope system can be adjustable on a linear stage. Optomechanical deformation caused by the weight of system itself and its temperature variation is analyzed by the finite element analysis (FEA). The results show that the deformation is estimated in the tolerance range. For the optic-axis alignment of telescope system, three-point alignment (TPA) method is chosen. The TPA method uses three parallel lasers and a plane mirror. Point source images were taken from collimated light and field observation. The performance of optical system was tested by point spread function and aberration measurement of the point sources.

The length of the feedhorn gets shortened from 12.5 mm to 11 mm, and it shows better side lobe level at the far-field patterns compared with the previous design. We looked into possible quasi-optical solution to match the feedhorn beam to the optics of the current ASTE telescope, starting from frequency-independent solution using two ellipsoidal mirrors to which wideband performance of the feedhorn naturally fits. We used a commercial physical optics package (GRASP) with an user-defined optimizer to give physical constraints to evaluated optical designs for highest efficiency.

We adopt the ASCOM driver platform to control the instruments through the integrated software. It can convert different interface libraries from various manufacturers into a uniform standard library. This allows us to effectively control astronomical instruments without modifying codes. We suggest a conceptual design of software for automation of a small telescope such as the new wide-field 0.25m telescope at McDonald Observatory.

The debris resulting from such processes remains as diffuse, low-surface brightness structures, such as outer disks, stellar halos, and faint companions. These structures will give us fruitful insight into the recent mass assembly history of galaxies, but it is challenging to observe them due to their low surface brightness. In order to explore the structural properties of outskirts of nearby galaxies, we conduct deep wide-field imaging survey with KMTNet. Here we present a progress report of data reduction for the images of NGC 1291, a lenticular barred galaxy with outer rings. To achieve accurate flat fielding, we use dark sky flat and remove the sky gradient of each exposure with a polynomial fit. As a result, we are able to reach 1 sigma depth of μ R ~ 29.6 mag arcsec -2. We expect to investigate the surface brightness profile of NGC 1291 in 1-D profile, and color-gradient in the outer part of the galaxy using the B- and R- band images. 항성및항성계 [ 포 ST-01] Raman O VI Profile Analysis of 58 / Bull.

It is known that it has a giant jet with physical size ~ 14pc. Its spectrum shows two strong emission bands at 6825Å and 7082Å, which are originated from Raman-scattering of O VI by neutral hydrogen atoms. We present the high-resolution spectrum of Sanudleak s star obtained with MIKE at the Magellan-Caly telescope to investigate the O VI emission region based on the profiles of the two Raman features. In this spectrum, it is noted that the Raman 6825Å feature exhibits a single broad peak profile, which is in high contrast with a clear triple peak profile of the Raman 7082Å feature. In our analysis we suggest that the O VI emission region consist of three main emission parts: an accretion disk, a bipolar outflow and an optically thick, compact component surrounding the white dwarf. By performing Monte Carlo simulation we constrain the representative column density of the H I scattering region N_HI 1 10^23 cm^ 2, which is in accordance with the observed flux ratio in the two Raman features F(6825)/F(7082) 4.5. parameters and the masses of stellar components.

70 기관소식 고등과학원 The Astrophysics and Cosmology group is headed by Prof. Changbom Park and Research Profs. Juhan Kim and Ho Seong Hwang. There are seven research fellows: Dr. Xiao-Dong Li, Dr. Hyunmi Song, Dr. Raphael Gobat, Dr. Stephen Appleby, Dr. Jihye Shin, Owain Snaith, and Dr. Motonari Tonegawa. Also Prof. Christophe Pichon at Institut d Astrophysique de Paris visited KIAS as a KIAS scholar for about three months in Prof. Park is carrying out the Korea Dark Energy Survey (KDES) project, which aims to uncover the nature of the dark energy component of the universe. Prof. Park is leading the Korean Scientist Group (KSG) participating in the Sloan Digital Sky Survey (SDSS) IV that started in July SDSS IV consists of three survey programs, APOGEE-2, MaNGA, and eboss. He is also a member of the Dark Energy Spectroscopic Instrument (DESI) consortium, which plans to construct a new wide-field multi-object spectrograph to carry out dark energy-related survey sciences. He has worked as the Editor-in-Chief of Journal of the Korean Astronomical Society. He is leading a group of astronomers, the Survey Science Group, which holds meetings to study and plan the future major astronomical survey projects. Individual members of the astrophysics group have been active in his/her research in Research Prof. Juhan Kim has been rebuilding the cosmological N-body simulation code (GOTPM). He adopted the Recursive Multi-Section technique to determine the local domain shape for better computing and network performances. He is also studying the cosmic matter-density evolution by solving the Euler equation analytically and numerically in the Lagrangian space. Also He has provided the KIAS group members with the processed data of the Horizon Run 4 simulation for the study of cosmology and galaxy formations. He has taken a managing role in preparing the Horizon Run 5, with which KIAS members will study the formation and evolution of galaxies in the cosmic volume with the RAMSES code. Research Prof. Ho Seong Hwang made a cosmological test of the Lambda Cold Dark Matter (LCDM) model by comparing the physical properties of large-scale structures of the universe between observations and simulations. He used the HectoMAP galaxy redshift survey and the Horizon Run 4 simulation for the comparison, and found that the size, richness and volume distributions of observed large-scale structures at intermediate redshifts are remarkably similar to the predictions of the LCDM model. He also tested the cosmic variance of galaxy number counts and examined the evolution of scaling relations for quiescent galaxies using the SHELS galaxy redshift survey. Dr. Sungwook E. Hong, who has move to KASI in the last December, published a paper on the properties of simulated galaxies from the Horizon Run 4 simulation, and worked with Dr. H. Song and Prof. C. Park to generate a mock AGN sample. Together with Dr. R. Gobat, he also published a paper on the evolution of galactic habitability in the universe. He is working on the conceptual design of a fiber-fed multi-object spectroscopy suitable for the Giant Magellan Telescope, as well as some instrumental collaborations with AAO in Australia and IUCAA in India. Dr. Xiao-Dong Li and Prof. Park applied the Alcock-Pacyznski (AP) test to the Sloan Digital Sky Survey III galaxies and put very tight cosmological constraints on cosmological parameters such as the density parameter and dark energy equation of state. Dr. Li is also working on a project using the shape of the 2-point correlation function across the line of sight to constrain the cosmological parameters from the volume effect, and another project applying the AP test using the 3-point correlation function. Dr. Hyunmi Song and Prof. Park have been trying to plant quasars in dark matter halos of a cosmological N-body simulation, Horizon Run 4, to generate mock quasar catalogs. Dr. Hyunmi Song, Prof. Ho Seong Hwang, and Prof. Park worked on the MMT/Hectospec redshift data in the field of the 한국천문학회보제 42 권 1 호, 2017 년 4 월 / 69

Dr. Raphael Gobat and Dr. S. Hong have worked on semi-analytic models of planetary distribution functions in galaxies across cosmic time, with an emphasis on habitable terrestrial planets. Dr. Raphael Gobat has also studied star formation rates and stellar population gradients in early-type galaxies at z>1.5. This represents the first direct confirmation of inside-out quenching in high-redshift non-star forming galaxies. Dr. Stephen Appleby joined the astrophysics group in September He has been working with Professor Changbom Park on Minkowski functionals and their generalization. Along with Dr. Dhiraj Hazra (PCCP) and Dr. Spyros Sypsas (APCTP) he works to solve the non-linear Schroedinger equation on cosmological distance scales, to calculate the power spectrum for a dark matter candidate with non-linear pressure support. Dr. Jihye Shin, together with Prof. Park, Prof. Kim, and Dr. Snaith, is preparing a large-volume and high-resolution hydrodynamic simulation, to be called Horizon Run 5. She published a paper on the low-end mass function of the Quintuplet cluster. She finished a project on hydrodynamic simulations of the central molecular zone with a realistic Galactic potential. Dr. Owain Snaith, along with Prof. Kim and Prof. Park, has studied the evolution of the gas power spectrum in cosmological simulations, especially how the power spectrum evolves depending on the resolution of the simulation initial conditions. He is working with Dr. J. Shin on a parameter study in order to tune the simulation code to observations, ready for the Horizon Run 5 simulation later in the year. He is studying dark matter halos in the Illustris simulation and is interested in exploring the chemical evolution of galaxies in simulations using a variety of approaches. Dr. Motonari Tonegawa, a new research fellow arrived at KIAS on December 1st, works on research topics such as the large-scale structure of the Universe, observational cosmology, and redshift surveys. He tries to measure the velocity dispersion of galaxies in virialized systems and its redshift evolution, through the Finger-of-God effect seen in the two-point correlation function of MMT spectroscopic sample, to compare with the prediction of General Relativity and other cosmology models. 부산대학교지구과학교육과 1. 인적사항본학과에재직하는 5명의전임교수중천문학교육과연구는안홍배, 강혜성교수가담당하고있다. 대학원에는석사과정에강서영, 박형욱, 서정빈, 성현미, 전희승, 정자희, 이수민, 정영주등 8명, 박사과정에는남기형, 서미라, 장운태, 조현진, 하동기등 5명이있으며모두과정을수료한상태다. 2. 연구및학술활동안홍배교수는국부우주 (z<0.01) 에있는은하중왜소은하의공간분포에대한연구를수행하고있다. 이중일부는 2016년 9월서울대학교에서개최된제10차 EAMA에서, 12월파리 AIP에서개최된 "The Physics of groups and galaxy properties therein" 에서연구결과를발표하였다. 안홍배교수는배현정과함께 SDSS 자료를이용하여 z<0.025안에있는 26,000개의은하를분석하여휜원반의환경분석을수행하였고그결과를 JKAS에게재하였다. 강혜성교수는은하단에서발견되는충격파에서우주선의가속과비열적복사에관한연구를수행하였다. 2016년 5월에미국 SLAC 연구소에서개최된 11th International Conference on High Energy Density Laboratory Astrophysics, 6월에미국 Monterey에서개최된 11th Annual International Conference on Numerical Modeling of Space Plasma Flows, 7월에일본 Tsukuba에서개최된 6th East-Asia School and Workshop on Laboratory, Space, & Astrophysical plasmas, 8월에미국 Minnesota 대학에서개최된 Physics of the Intracluster Medium: Theory and Computation, 9월에이탈리아 San Vito di Cadore에서개최된 Cosmic Ray Origin Beyond the Standard 70 / Bull.

Masateru Ishiguro 회원은서울대학교에서태양계내 74 / Bull. Kor. Astron. Soc. Vol. 42 No.1, Apr. 2017

76 기관소식 의소행성과혜성을연구하여태양계의진화양태와천체들의물리적특성을밝히는연구를진행하고있다. 2016년에는해당그룹에서 4개의 SCI 논문 ( 주저자 / 책임저자논문 3개포함 ) 을발표했는데, 주요내용은다음과같다. (1) Masateru Ishiguro, 권유나, 김윤영및이명균회원이주도한연구로 2014년 12월에있었던혜성 15P/Finlay의폭발현상이후 2015년 1월에또다른폭발이있었음이알려졌다 (Ishiguro et. al., 2016a). 또한먼지방출을모형화한수치모형을통해최대약 570 km/s의속도로 10만톤의먼지가이폭발로방출되었음을보였다. 이논문에서또한 15P/Finlay와같은폭발은대략연간 1.5회정도발생하며, 이러한폭발들이평균적으로초당 10kg이상의입자를행성간공간으로주입시킨다는것이유추되었다. 상술한수치모형으로부터이천체에서방출된먼지는다공질의어두운입자들임이알려졌고, 이는그러한입자가혜성내부에존재하며폭발시에방출될수있음을시사한다. (2) 권유나회원과 Masateru Ishiguro, 김윤영및이명균회원의주도로목성계혜성인 17P/Holmes가 2014 년근일점을지나던시기의관측연구결과가출판되었다 (Kwon et. al., 2016). 해당논문은지난 2007년근일점을통과하며하루만에 100만배가량밝아졌던 17P/Holmes 혜성이그이후처음으로근일점을통과하는동안먼지방출률 ( 생성률 ) 이어떻게변화하는지를관측하고이론적으로모형화했다. 이연구로근일점에가까워지고멀어지는동안먼지의생성률이비대칭적으로변하며, 지난 2007년근접시에비해먼지생성률이 10만배가량작아졌음을보였다. 이는혜성표면에서먼지를방출하는영역의넓이가 100배정도줄었음을의미하며, 논문에서는이론적계산을통해열적표피깊이가 7년만에급격하게깊어졌음을보였고, 현재약 5cm 이상의먼지층이표면을덮어버렸음을보였다. (3) Masateru Ishiguro 회원과김윤영, 권유나회원등은상술한 17P/Holmes가 2007년보였던대규모폭발현상에대한조사를실시했다 (Ishiguro et. al., 2016b). 이논문에서는 17P/Holmes의혜성구조가단순한구조가아니라최소 2개층위의구조 ( 핵에가까운먼지구름과좀더길게퍼져있는구조 ) 로이루어졌음을앞서와같은수치모형을통해알아내었다. 동시에먼지층은약 1-10mm크기의먼지입자로구성되어있으며, 초기에 50 m/s 이상의속도로방출되었고, 이는혜성표피에있던얼음성분의급작스런승화에의한것임을주장하였다. 방출된질량은약 4~8억톤규모로추정되었다. (4) Masateru Ishiguro 회원이참여한공동연구에서쪼개진혜성인 332P/Ikeya-Murakami 의운동학에대한연구가실시되어출판되었다 (Jewitt et. al., 2016). 해당연구에서는 332P/Ikeya-Murakami 가기존에알려진것 보다매우작은약 275m 미만의반경을가지며, 따라서최소약 300배가벼운천체였음이밝혀졌다. 또한혜성의질량이작기때문에혜성의자전불안정성이과거의모체로부터파편을날리는데주요한역할을했을것이라는점이제안되었다. Sascha Trippe's group focused mainly on the physics of the central parsecs of active galactic nuclei (AGN). They conducted interferometric observations using the Korean VLBI Network (KVN) and the KVN and VERA Array (KaVA) within the frame of the Plasma-physics of Active Galactic Nuclei (PAGaN) project which is aimed at understanding the formation, collimation, and propagation of AGN jets. Their group is part of the AGN Working Group of the Korean-Japanese KaVA Science Group, the East-Asian AGN working group, and the East-Asian VLBI Network (EAVN) collaboration. They were awarded a 3-year KASI-University Cooperation Grant for exploring a new approach to optical interferometry. Additional research projects were targeted at the dynamics of early-type galaxies and the polarization of cosmic microwave background radiation. Notable science results were (a) the discovery of a relation between the time scale of AGN variability and accretion rate, (b) the finding that oscillations of electric charges caused by gravitational waves might contribute to the polarization of the cosmic microwave background, and (c) the discovery that systematic deviations from the virial relation observed for early-type galaxies are caused by a scaling of ellipticity with galaxy mass. Two group members were awarded research prizes: Junghwan Oh received the KAS Rising Star Award, Sascha Trippe received the JKAS Award. 3. 발표논문 Aasi, J.; Abbott, B. P.; Abbott, R.; Abbott, T.

M. Van Putten's research group includes two new graduate students with a focus on (i) searchesfor broadband extended gravitational wave emission from nearby core-collapse supernovae; (ii) weak gravity in cosmology and galactic dynamics; and (iii) searches for moons around exoplanets with the upcoming James Webb Telescope (JWT). His is a member of the KAGRA gravitational wave detector in Japan, a newly established CRC Center for High Energy Astrophysics (CHEA), UNIST, and frequently collaborates with Pr. M. Della Valle (Director of the Observatory of Naples, Italy) and Pr. A. Levinson (Tel Aviv University). His research is supported by an individual NRF grant (50 MWon/year) and CHEA (1.5 BWon/year). His research on strong and weak gravitation was recently presented in an invited colloquium at the University of Western Australia (UWA), Perth, Australia, and has been featured by two Press Releases (Sejong University and INAF, Italy). For deep searches of GW-waves, he developed a new butterfly filter implemented on a newly constructed heterogeneous 44 teraflop GPU-CPU platform under OpenCL. It operates at 80% efficiency normalized to clfft. At 26 million template second performance, it defines the most sensitive search algorithm for gravitational waves ever for the high frequency regime of Hz relevant to core-collapse SNe. He developed a theory of weak gravity with explicit expressions for dynamical dark energy and Milgrom's law (equivalent to the baryonic Tully-Fisher relation) in terms of the Hubble and deceleration parameter of three-flat Friedmann-Robertson-Walker universes.

83 2017 봄학술대회 a remarkably sharp transition recently identified in high resolution galaxy rotation data. Continuing work on strong and weak gravity aims at a deep search for GW bursts in all of LIGO S6 on an extended 128 teraflop GPU-CPU system; a confrontation of weak gravity with with recent data on the Hubble parameter and Manga data on galaxy rotation curves; and the development of methods to search for moons around exoplants with JWT. In a separate development, he co-developed a theory of exponential growth in anthropogenic earthquakes and statistic analysis of risk based on a running b-values. With no priors, the proposed new method is fundamentally different from the commonly used Gutenberg-Richter b-value that is based on a somewhat arbitrary choice of cut-off in distributions of magnitude. A specific prediction relevant to the Groningen earthquakes in The Netherlands (over 120 events per year in 2016) is an exponential increase to about one event per day in It predicts an adverse outlook on fractures, from high frequency more so than high magnitude events. His teaching on mathematical astronomy has been accepted for publication by SpringerNature, in "Introduction to Methods of Approximation in Physics and Astronomy", April 2017, to appear. G. Rossi has been working on several cosmological aspects related to the SDSS-IV survey, with a focus on the Lyman-Alpha forest and on massive and sterile neutrinos. In particular, he has developed a new suite of hydrodynamical simulations that will be useful for studying the impact of these particles on cosmological structures; the simulations were produced using the KISTI supecomputer Tachyon2 under allocation KSC-2016-G In January 2016, he became the co-leader of the newly formed SDSS-IV eboss simulations working group, and took over on the management of the National Energy Research Scientific Computing Center (NERSC) computational facilities (Cori and Edison) for the collaboration. During 2016, G. Rossi has also expanded his cosmology group with the addition of new students - all actively involved in the SDSS-IV - and invited and hosted several visitors, among which Prof. Suto from the University of Tokyo. In collaboration with the Italian Embassy, G. Rossi has organized the `1st Korea-Italy Symposium on Cosmic Microwave Background Science and Cosmology at Sejong University, along with two institutional visits to KASI and the IBS headquarter by an Italian delegation - with the goal of bringing for the first time CMB science in Korea, a scientific field in which Italy detains a strong leadership especially in connection with the Planck satellite. The meeting was also pivotal for initiating the planning of the Busan 2021 XXXI International Astronomical Union (IAU) General Assembly, as the IAU General Secretary, Professor Piero Benvenuti, visited BEXCO and interacted with the top leaders of the Korean IAU and KAS. The meeting led to join the planned Stage-IV CMB experiment CORE, and G. Rossi also received an Italian Bilateral Scientific Cooperation Award Nomination by the Italian Ministry of Foreign Affairs for a significant contribution to the advancement of science and technology, thus improving Italy's S&T relations with foreign countries. Since last January 2016, he has presented results of his research in several national and international conferences and meetings (12), and gave a total of 19 invited colloquia and seminar talks, along with a public talk at the Italian Embassy. During the Summer 2016, he was also a CAASTRO research scholar at the University of Queensland in Brisbane, Australia. 3. 연구및교육시설세종대학교가보유하고있는가장중요한관측시설은 76cm 반사망원경이다. 소백산국립천문대에서곤지암노곡리세종대부지로이전 설치한 2012년이후망원경의구동부등에이상이있어사용하지못하였다. 에스엘랩에의뢰하여 2015년부터망원경의구동, 제어부와부경을수리하여정상화를달성하였다. 76cm 반사망원경은학부생들의관측실습및공개행사등에사용될예정이다. 곤지암추곡리관측소에는 40cm 반사망원경이설치되어있지만지난수년간사용을하지못하였는데, 작동상태를면밀히검토하였으며수리계획을수립하여정상화를이루고자노력하고있다. 40cm 망원경또한학부생들의관측실습및공개행사등에사용될것이다. 학부학생들의관측실습은교내영실관옥탑의간이관측소에설치되어있는 11인치반사망원경및다수의소형굴절망원경을이용하고있다. 또 SRT 소형전파망원 82 / Bull.
