Because their shallow potential wells respond sensitively to both internal feedback and external perturbations, they are ideal laboratories for testing how environment shapes galaxy evolution — and for probing the nature of dark matter itself. A particularly puzzling population is that of diffuse, low-surface-brightness galaxies (LSBGs), including ultra-diffuse galaxies (UDGs), whose extended and faint stellar structures are difficult to explain with a single formation channel. Our research group is currently using the IllustrisTNG simulations to characterize the population of diffuse galaxies and LSBGs and to identify the physical drivers of their extended structures. This project will extend that work substantially: the student will use DARWIN, our own suite of cosmological hydrodynamic simulations dedicated to dwarf galaxy formation and evolution, to investigate the environmental transformation of dwarf galaxies at a resolution and level of physical detail that large-volume simulations cannot reach. The specific aims are:  - To quantify how environment drives the structural and star-formation transformation of dwarf galaxies.  - To separate the relative contributions of the physical mechanisms responsible — ram-pressure stripping, tidal heating and stripping, starvation, and internal feedback — as a function of halo mass and infall time.  - To determine which of these channels produces diffuse, low-surface-brightness dwarfs, and to predict their observable properties for upcoming deep imaging surveys. The student will analyze the DARWIN simulation suite, a multi-tier set of RAMSES-based cosmological simulations (DARWIN-1 full-box, DARWIN-2/-3 zoom-in) designed specifically to resolve the internal structure of dwarf galaxies. The work will combine (i) statistical analysis of the dwarf population in the full-box run, (ii) high-resolution zoom-in simulations of selected dwarfs and their host environments, and (iii) orbit and merger-tree based reconstruction of each galaxy's environmental history. Results will be cross-compared with IllustrisTNG to distinguish robust physical trends from resolution- and subgrid-dependent behavior. Simulated galaxies will be converted into mock observations to allow a direct comparison with observational data, in particular with the deep low-surface-brightness imaging from K-DRIFT and with forthcoming LSST/Euclid data. In the later stage, the student may extend the analysis to alternative dark matter models within the nextDARWIN framework, testing whether the diffuse dwarf population carries a dark-matter signature.Expected outcomes:  • At least three first-author papers in leading international journals (e.g., ApJ, MNRAS, A&A), plus co-authorship on DARWIN collaboration papers.  • A publicly releasable catalog of simulated dwarf galaxies with full environmental histories and matched mock images.  • An analysis pipeline connecting simulations to low-surface-brightness observations, directly supporting the K-DRIFT science program.  • Presentations at domestic (KAS) and international conferences, and research experience abroad through our collaboration with Observatoire astronomique de Strasbourg.  • Training of a researcher fluent in both numerical simulation and observational data analysis — a profile increasingly required in the survey era. 3. 한정열 교수 (jhan@kasi.re.kr) 모집과정 : 박사과정 또는 석박사 통합과정 (근무실: 빛마름동)  0) 연구 개요   - 천문우주용 관측기기 기술개발을 위한 연마 및 조립정렬 기술 연구   - 천문우주 관측데이터 특성에 따른 최적의 데이터 분석기술 연구   - 천문우주 망원경 광기계 설계 및 해석 연구  1) 연구목표   - 천문우주용 대형광학계 반사경 개발기술 현황을 이해한다.   - 국내외 첨단 광학계 개발동향을 이해하고 중장기적 광학기술 개발 안목을 가지게 된다.   - 천문우주용 반사경의 연마기술을 이해할 수 있다.   - 반사경의 공구영향함수(Tool Influence Function; TIF)를 이해할 수 있다.   - 망원광학계의 조립 및 정렬 절차를 이해하며, 조립정렬 데이터 분석을 통해 조립정렬 공정에 참여한다.   - 천문우주기술 분야 빅데이터 분석을 위한 데이터 수집계획을 수립하고 분석할 수 있다.   - 천문우주용 대형광학계의 광기계 기술개발 현황을 이해한다.   - 국내외 첨단 광학계 개발동향을 이해하고 중장기적 광학기술 개발 안목을 가지게 된다.   - 천문우주용 대형광학계 광기계 설계 및 해석기술을 이해하며 첨단 광기계기술을 연구할 수 있다.  2) 연구방법  - 국내외 천문우주용 대형광학계 반사경 개발기술 관련 문헌을 조사하고 연구소모임을 통하여 관련지식을 공유한다.  - 천문우주용 반사경의 연마기술 관련 연구자료를 확보하고, 정기적인 논문발표를 통하여 참고문헌에 대한 정교한 지식을 습득하며, 천문연에서의 연구개발의 novelty를 이해한다.  - 반사경의 공구영향함수를 획득하고 분석하여 연마공정을 최적화할 수 있도록 지도교수와 정기/비정기 미팅을 통해 연구역량을 증진시킨다.  - 망원광학계의 조립 및 정렬절차에 대해 기존 천문연에서의 조립정렬 경험을 이해하며, 기존 자료를 기반으로 새로운 광학계 개발 시 활용할 수 있는 정렬 알고리즘을 개발 및 적용한다.  - 천문우주기술 분야 빅데이터 포맷을 이해하고 해독하며 데이터 가시화를 통해 데이터간 융합정보를 분석하고 정규 팀미팅을 통하여 연구내용을 공유한다.  - 국내외 천문우주용 대형광학계 개발기술 관련 문헌을 조사하고 연구소모임을 통하여 관련지식을 공유한다.  - 천문우주용 대형광학계 광기계 분야의 핵심연구자료를 확보하고, 정기적인 논문발표를 통하여 참고문헌에 대한 정교한 지식을 습득하며, 국내외 전문가를 통하여 전문지식을 습득한다.  - 망원광학계의 광학 및 광기계 설계연구에 참여하여 기존 방식의 망원경에서 구현한 기술을 이해하고, 새로운 연구방법론을 적용하여 첨단 망원경을 개발한다.  3) 기대결과  - 천문우주 분야에 적용할 수 있는 대형 첨단 반사광학계 개발기술의 국내외 동향을 이해하고, 세계적인 경쟁력을 갖춘 연구수행이 가능하다.  - 국가경쟁력을 높일 수 있는 신개념의 연마기술을 개발하며, 점차 다양하고 대형화하며 복잡해지는 광학계 개발 시 조립 및 정렬을 가능하게 한다.  - 방대한 데이터가 산출되는 시대에 걸맞는 데이터 분석 전문가를 양성하여 국가적으로 반드시 필요한 인력 자원을 확보한다.  - 천문우주 분야에 적용할 수 있는 대형 첨단 망원경 광기계 기술의 국내외 동향을 이해하고, 세계적인 경쟁력을 갖춘 연구수행이 가능하다.  - 국가경쟁력을 높일 수 있는 신개념의 광기계기술을 개발하며, 점차 다양하고 대형화하며 복잡해지는 광학계 개발 시 광기계 설계가 가능하게 된다. 4. 안교훈 교수 (kyohoon@ust.ac.kr) 모집과정 : 박사과정 또는 석박사 통합과정 (근무실: 장영실홀) Research on Space Optical Communication Systems for Astronomy and Space Science Optical communication enables ultra-high-speed as well as high-capacity data transmission and provides high security due to its higher frequencies and narrower beamwidth compared to conventional RF communication. However, atmospheric turbulence distorts received signals and interferes with precise beam alignment during the Pointing, Acquisition, and Tracking (PAT) process. These factors specifically degrade the performance of optical communication channel between an optical ground station and a satellite. With the advent of the "New Space" era, the satellite-based optical and quantum communications have been considered as a critical national strategic technology. Consequently, there is a growing need to compensate the signal distortion caused by atmospheric turbulence and to improve the precision of PAT systems. Korea Astronomy and Space Science Institute (KASI) has been developing core technologies for next-generation optical ground stations and satellite payloads to ensure stable communication links by overcoming atmospheric turbulence environments. Students in this program will gain an understanding of atmospheric turbulence models and participate in research on high-reliability PAT technologies development under atmospheric turbulence and transmitter jitters. To achieve this, students will select one or more of the following research topics and then conduct research under the guidance of co-advisors. [Research Objectives]  - Research on atmospheric turbulence analysis and compensation for enhancing the stability of ground-to-satellite optical and quantum communication links   - Research on the development of precise PAT control systems under atmospheric turbulence for ground-to-satellite and satellite-to-satellite optical communications [Research Methodology] Theoretical study and simulation of atmospheric turbulence modeling and characteristics of optical communication signal distortion under turbulent conditions Development of precise PAT algorithms and control program to correct atmospheric turbulence for ground-to-satellite and satellite-to-satellite optical communications, based on Matlab or Python. [Expected Impact]  - Supplying specialized personnel related to space optical and quantum communications through theoretical training and development experience.  - Producing key human resources for deep space optical communications of L4 mission.   - Contributing to the global competitiveness in the field of national strategic space technologies of optical and quantum communications through the development of enhanced technologies of atmospheric turbulence compensation. 5. 이민영 교수 (mlee@kasi.re.kr) 모집과정 : 박사과정 또는 석박사 통합과정/석사과정 (근무실: 장영실홀) The Square Kilometre Array (SKA) is a next-generation radio telescope that is currently being built in Australia and South Africa. It operates at low frequencies of 50 MHz~15.4 GHz and will become the most powerful observing facility once completed in 2030. We are preparing the upcoming SKA era by utilizing a number of pathfinder telescopes, including ASKAP. The GASKAP-HI survey is an ongoing survey with ASKAP to map HI in the Milky Way and the surrounding Magellanic System (Large Magellanic Cloud, Small Magellanic Cloud, Magellanic Bridge, and Magellanic Stream), and a successful candidate will use high-resolution, high-sensitivity HI data from the GASKAP-HI survey to perform the following projects: Aims: 1) Probe the properties of HI in a wide range of environments 2) Examine the atomic-to-molecular transition in the interstellar medium Methods: The candidate will analyze HI emission and absorption spectra to estimate the physical and dynamical properties of HI and compare the results to state-of-the-art theoretical models to understand what determine(s) the properties of HI in a wide range of environments. In addition, the candidate will compare the analyzed HI spectra to other multi-wavelength data (e.g., ALMA CO and HCO+ observations) to examine the conditions for the atomic-to-molecular transition in the interstellar medium.  Outcomes: The candidate will provide comprehensive insights into the roles of HI in the formation of molecular clouds and stars. With extensive experiences with pathfinder data, the candidate will also be best-suited for performing SKA key science projects in the near future. 6. Thiem Hoang 교수 (thiemhoang@kasi.re.kr) 모집과정 : 박사과정 또는 석박사 통합과정 (근무실: 이원철홀) Dust Dynamics and Evolution in Planetary Systems We invite applications from highly motivated candidates for one Ph.D. or Integrated Ph.D. position in theoretical and computational astrophysics at the Korea Astronomy and Space Science Institute (KASI), under the co-supervision of Dr. Thiem Hoang at KASI and Dr. Pierre Henri at the Observatoire de la Côte d’Azur, France. The successful candidate will investigate dust dynamics and evolution in planetary systems, from magnetized planet-forming environments to comets and interstellar objects. Dust provides the building blocks of planets, and its growth, alignment, transport, and destruction—shaped by gas, radiation, and magnetic fields—play critical roles in planet formation. Comets preserve primitive material from our Solar System, while interstellar objects carry information about other planetary systems and their birth environments. This research is particularly timely because the Comet Interceptor mission may encounter either a pristine comet or an interstellar object. Connecting remote observations with its in situ measurements will help trace dust evolution, constrain the origins of interstellar objects, and test dust-physics theories under diverse conditions. The research will focus on: (1) modeling dust dynamics and evolution and the resulting emission and polarization, together with numerical simulations and synthetic polarization observations, to study dust physics during planet formation; (2) and developing physical dust models to interpret in situ measurements from spacecraft flyby missions and using these observations to test theories of dust physics in cometary environments and interstelallar objects. 7. 김영민 교수 (ymkim@kasi.re.kr) 모집과정 : 박사과정 또는 석박사 통합과정 (근무실: 대덕전파천문대) 중력파원 시뮬레이션 연구 * 연구목표  - 중력파 발생 천체에 대한 상대론적 수치 시뮬레이션 코드 개발 및 이를 활용하여 중력파 천문학 및 다중신호 천문학 연구를 목표로 한다.   1) 고밀도,고중력 천체 및 그 주변 물질에 대한 상대론적 시뮬레이션   2) 상대론적 유체역학 시뮬레이션을 통한 중력파 발생 천체 (회전하는 중성자별 등) 시뮬레이션   3) 상대론적 시뮬레이션의 초기 조건 및 수치 도구에서 정확하고 효율적인 알고리즘 개발 * 연구방법  - 상대론적 유체역학 코드 개발  - 중성자별과 같은 고밀도,고중력 천체 및 그 주변 물질에 대한 시뮬레이션을 통해 중력파 천문학 및 다중신호 천문학 연구 진행  - 연구주제에 따라 필요한 경우, LIGO Scientific Collaboration 또는 Einstein Telescope (ET) collaboration 가입을 통해 국제공동연구를 진행함. * 기대결과   - 중력파 천문학 및 다중신호 천문학 연구분야에서 중력파 발생 천체에 대한 정밀한 수치 시뮬레이션을 통해 관련 분야 전문가로서 주도적인 역할을 할 수 있는 연구자로의 성장 모집과정 : 박사과정 (근무실: 빛마름동) Gravitational-wave detection technology development (High-Precision Adaptive Mode-Matching Systems: Spatial Mode Sensing and Deformable Mirror (DM) Development for Ultra-Sensitive Optical Cavities) Aims: Develop an integrated adaptive optics framework to suppress spatial mode-mismatch loss below 1 % in precision cavities, minimizing Higher-Order Mode (TEM_{nm}) losses and phase degradation.

Therefore, developing observational technologies for real-time monitoring and forecasting of space weather conditions is critical. The Korea Astronomy and Space Science Institute (KASI) is currently developing technologies to monitor and predicting ionospheric conditions in near-real-time by using GNSS observation network. Furthermore, to investigate Sun-Earth interactions, KASI has developed and deployed ROKITS (Republic Of Korea Imaging Test System), a spaceborne wide-field imaging camera, to collect aurora and airglow observations from space. Key Research Tasks for the Candidate: This research focuses on analyzing the quality and performance of ionospheric and upper atmospheric data collected from both ground-based and spaceborne segments. Specifically, the selected student will:   - Validate ROKITS performance: Conduct comparative analysis of ROKITS imagery (aurora/airglow) against ground-based all-sky camera networks or data from other satellites.  - Mission planning: Design observation campaigns to establish robust validation scenarios.  - System optimization: Based on the analysis, derive advanced data processing algorithms or propose operational improvements to maximize the observational efficiency. 9. 홍성욱 교수 (swhong@kasi.re.kr) 모집과정 : 박사과정 또는 석박사 통합과정 (근무실: 이원철홀) Understanding Large-scale Structures of the Universe using Massive Cosmological Simulations and AI  - Train deep learning models using gas distribution data from the Horizon Run 5 and DARWIN hydrodynamic simulations, and apply the learned gas information to large-volume N-body simulations.  - Use machine learning techniques to learn the merger history characteristics of SDSS/DESI LRG/ELG/QSO candidates from Horizon Run 5, and apply these to dark matter halos in N-body simulations to generate mock observational data for future cosmological model analysis.  - Reconstruct galaxy distributions without redshift distortions and corresponding dark matter distributions from distorted galaxy distributions using deep learning techniques.

Because dark matter does not emit light, its properties must be inferred from its gravitational effects on galaxies, galaxy clusters, and the large-scale structure of the Universe. In particular, the faint outskirts of galaxies, low-surface-brightness galaxies, stellar streams, and diffuse intracluster light provide sensitive tracers of dark matter because their structures are strongly influenced by the gravitational potential of dark matter halos. The K-DRIFT (KASI Deep Rolling Imaging Fast Telescope) project is designed to explore this extremely faint regime of the Universe. Its wide field of view and low-scattered-light optical system enable systematic observations of diffuse structures that are difficult to detect with conventional telescopes. The project therefore provides a unique opportunity to investigate dark matter over a wide range of physical scales, from dwarf galaxies to massive galaxy clusters. The student will conduct observational and/or simulation-based research using K-DRIFT data together with complementary data from major astronomical surveys and facilities. Depending on the student's interests and the development of the K-DRIFT survey, the PhD research may focus on one or more of the following topics: Ultra-diffuse, dark, and dark-matter-deficient galaxies: investigating unusual galaxy populations whose stellar and dynamical properties may provide strong constraints on the relation between galaxies and dark matter halos.Stellar halos and tidal streams: tracing past galaxy mergers and interactions through extremely faint structures in galaxy outskirts and using their morphology and perturbations to probe the underlying gravitational potential and dark matter substructure.Galaxy groups and clusters: studying diffuse intracluster light, satellite galaxy populations, and cluster dynamical states to understand how baryonic matter and dark matter are assembled during hierarchical structure formation.The ultimate goal of this PhD project is to use the low-surface-brightness Universe as a laboratory for dark matter research.Expected outcomes include peer-reviewed publications, presentations at domestic and international conferences, participation in K-DRIFT survey activities, and collaboration with researchers working on observational astronomy, astronomical instrumentation, numerical simulations, and dark matter theory. 11. 정웅섭 교수 (jeongws@kasi.re.kr) 모집과정 : 석박사 통합과정 (근무실: 이원철홀) High-Redshift Infrared-Luminous Galaxies Most of galaxies at the Comsic Noon when star formation and supermassive black hole growth were most active are heavily obscured by dust, making it difficult to fully understand their physical properties and evolution through optical observations alone. In particular, dust-obscured galaxies and active galactic nuclei (AGNs) in the high-redshift Universe are important targets for investigating star formation in galaxies, the growth of supermassive black holes, and their coevolution. Systematic studies of these objects require spectral analyses that combine multiwavelength observations from optical to infrared wavelengths. The selected student will participate in SPHEREx (PI institue: Caltech), NASA’s all-sky infrared spectrophotometric space mission operated through an international collaboration, and will conduct a range of studies on high-redshift galaxies. Using SPHEREx’s 0.75–5 μm all-sky spectroscopic data, the student will search for infrared-bright high-redshift objects, determine their redshifts and physical properties, and investigate dust-obscured luminous galaxies and candidates hosting supermassive black holes. The student will also combine multiwavelength data and follow-up observations from space telescopes and large ground-based telescopes to study galaxy star formation, black hole growth, and the environments surrounding these systems. The program aims to train researchers who can analyze large observational datasets from next-generation infrared space telescopes and take a leading role in infrared galaxy research. 12. 박성홍 교수 (shpark@kasi.re.kr) 모집과정 : 석박사 통합과정 (근무실: 대덕전파천문대) Aim: The primary aim of this project is to investigate the rapid release and conversion of energy in the solar atmosphere using state-of-the-art solar radio observations. The main focus will be on solar flares and coronal mass ejections (CMEs), with particular emphasis on understanding magnetic reconnection, plasma heating, shock formation and propagation, various types of radio bursts, and particle acceleration. Depending on the student’s interests, the research may also include solar wind studies using interplanetary scintillation (IPS), magnetic field studies of CMEs and the interplanetary magnetic field (IMF) using Faraday rotation, and analogous eruptive and radio phenomena on other stars. Methods: The student will primarily analyze state-of-the-art solar radio observations, including dynamic spectra, imaging, and polarization data, together with complementary multi-wavelength observations. These observations will be used to investigate magnetic reconnection, plasma heating, shocks, radio emission, and particle acceleration during solar eruptive events. Depending on the research topic, IPS and Faraday rotation observations may also be analyzed. Theoretical modeling and numerical simulations may be used when needed to interpret the observations and investigate the underlying physical processes. Expected Outcomes: The project is expected to improve our understanding of how energy is rapidly released and converted into plasma heating, particle acceleration, shocks, and radio emission during solar flares and CMEs. Additional studies may provide insights into solar wind properties, CME and IMF magnetic fields, and analogous eruptive phenomena on other stars. The student will develop research expertise in solar radio astronomy, solar and heliospheric physics, observational data analysis, and, where appropriate, theoretical modeling and numerical simulations. 13. 윤혜인 교수 (hiyoon@kasi.re.kr) 모집과정 : 박사과정 또는 석박사 통합과정 (근무실: 장영실홀) The gas properties of galaxies and their role in galaxy evolution using SKA precursor telescopes and multi-wavelength observations  Aims: (i) Investigate the role of cold gas in galaxy evolution by combining the wide-field ASKAP HI absorption survey with CO and optical data, tracing galaxy evolution across cosmic time and the link between cold gas and nuclear activity. (ii) Investigate the role of environment in galaxy evolution using high-resolution HI emission data, revealing how gas accretion, depletion, and redistribution vary across environments of different densities and drive galaxy evolution. Methods: The student will analyze HI absorption and emission data from ongoing SKA precursor surveys (ASKAP, MeerKAT) and radio interferometric observations (VLA, KVN, etc.). Multi-wavelength follow-up with ALMA and Gemini will add information on molecular gas, star formation, and galaxy environments, linking gas distribution and kinematics to the physical properties of galaxies. Expected outcomes: The project will provide new observational constraints on the gas content and evolution of galaxies, identify the physical processes driving gas accretion and removal, and build a multi-wavelength synergy for the gas–galaxy connection. The student will gain expertise in radio interferometry essential for the SKA era, large-scale survey analysis, and multi-wavelength astronomy, with strong potential for high-impact publications and opportunities to present at international conferences and collaborate with researchers worldwide. 14. 박재흥 교수 (pj@kasi.re.kr) 모집과정 : 석사과정 (특별전형 위탁생) (근무실: 태양관측동) This project for the Master’s course is aimed at developing a CubeSat that can be used for both space science and national defense.
