A list of PhD projects for the fall semester in 2018 is following:

1. Prof. Bong Won Sohn  (bwsohn@kasi.re.kr)

This is a PhD project and joint research project with INAF/IRA Bologna. The student is expected to participate our joint research program. We intend to address the issue of the actual triggering of the black hole activity. Therefore, we will aim at the selection of SMBH with very young jets, i.e. jets that have just started making their way out of the SMBH through the galaxy. These sources were selected on the basis of their spectral and temporal variations, a process that is already under way from our team, both using existing data and acquiring new ones with Korean and Italian telescopes. This includes also studies of the bright young radio source 3C84 and newly found sources from recent weka Blazar surveys. The student is supposed to conduct KVN, KaVA, EVN, and EATING VLBI observations and data analysis.

2. Prof. Arman Shafieloo (shafieloo@kasi.re.kr)

Inflation is predicted to generate primordial gravitational waves that left the imprint as pinwheel-like (B-mode) patterns in the CMB polarization map.

However, the recent joint analysis of BICEP2/Keck Array and Planck data has revealed that the first detection of CMB B-modes is only achieved when Galactic dust polarization is accurately modeled and separated from the CMB polarization data. 

The successful candidate will be part of an international team to work on developing a self-consistent physical model of Galactic dust polarization by linking grain alignment to dust properties and local physical conditions of the interstellar medium. An important goal of this project is to apply the self-consistent polarization model to constrain the physics of the early universe with the CMB polarization as well as the physics of the interstellar medium. Students will be trained to master a wide range of research skills, including analytical and theoretical ability, numerical modeling and computational simulations.

Origins of Gamma-ray Flares in Active Galactic Nuclei: 

Gamma-ray flares of Active Galactic Nuclei (AGN) are known to be occurred in innermost regions of relativistic jets which radiate in whole ranges of electromagnetic spectra due to synchrotron radiation, synchrotron self absorption, inverse-Compton scattering, Doppler boosting etc. Here we may raise two questions on the nature of the gamma-ray flares of AGN such as: a) What is the basic cause of the gamma-ray flares from AGNs? b) What is the physical process of the causes? For the first question, there are several suggestions like 1) a relativistic jet of high energy plasma, 2) Doppler boosting of synchrotron radiation of the jet, 3) inverse Compton scattering by relativistic electrons, etc. For the second question, we may find some candidates and detail mechanism for the gamma-ray flares such as 1) compression and heating of the plasma in the relativistic jets, 2) generation of the relativistic particles, 3) rapid variability in flux and magnetic field. In order to answer to the questions, we may conduct either 1) studies of large samples of flaring AGNs for investigating statistics and correlation of observed properties, 2) multi-wavelength observations of individual objects for testing time profiles of flares, for studying physical properties of emission features (jet knots), and studying evolution of SEDs , or 3) polarization observations for looking at magnetic field environments. Possible explanations of the gamma-ray flares in AGNs are a) shocks-in-jets propagating within jet flow and b) bending of the whole jets. For both cases, we should expect changes in polarization, luminosity, particle distribution, and structures of jets at mas-scale. The multifrequency simultaneous VLBI/SD observations with Korean VLBI Network are one of the best tools for detecting such changes correlated with gamma-ray flares. A key science program of KVN aims to answer the fundamental questions about the basic nature of the flares of AGN. The Interferometric Monitoring of Gamma-ray Bright AGNs (iMOGABA) project has been launched in 2015 as a key science program of KVN. This project uses KVN for monthly interferometric monitoring of more than 30 gamma-ray bright AGN at 22, 43, 86, and 129 GHz simultaneously (see http://radio.kasi.re.kr/sslee for preliminary results). The iMOGABA aims especially at the potential connection between gamma-ray outbursts and the formation of new jet components, by investigating the potential correlation of the gamma-ray light curves with the brightness and mas-scale structures of the inner jets. The monitoring cadence of a month and the observing frequencies of 22-129GHz make this project unique in studying the gamma-ray flaring AGN. Students will be actively involved in this project and leading stuides on individual AGNs in this program.

 ▶ 연구목표: 인공위성 레이저추적(SLR) 시스템은 레이저를 이용하여 인공위성까지 거리를 mm 수준으로 측정하는 가장 정밀한 인공위성 추적 시스템이다. 통계적 방법과 상관기법을 바탕으로 배경잡음 및 Dark current 잡음으로부터 실제 인공위성으로부터 반사되어 되돌아오는 신호를 구별하는 연구를 수행한다.

 ▶ 연구방법: Two-way 경로 투과율은 낮과 밤의 잡음, 기상 상태에 따라 달라 경험으로부터만 유추할 수 있기 때문에 검출한 신호가 인공위성으로부터 오는지 또는 외부 잡음인지 구별하는 것은 불가능하다. 그러나 검출된 신호들로부터 상관 파라미터와 프레임 시간을 결정함으로써 잡음 신호를 구별하여 신호포착 여부를 결정할 수 있다. 기존 방법은 인공위성 레이저추적 시스템 사양, 오경보 확률과 신호검출 확률 조건에 따라 새로운 Fitting 방정식을 적용하므로 정밀하지 않고 복잡하다. 따라서 신호검출 확률과 오경보 확률 모델의 특성을 분석하여 조건 방정식(Conditional equation)을 유도하여 보다 정밀한 상관 파라미터와 프레임 시간을 결정하는 연구를 수행한다. 이러한 방법으로 도출된 상관 파라미터 및 프레임 시간은 실제 인공위성 레이저추적 데이터를 이용하여 분석하고 검증한다.

 ▶ 기대효과: 본 연구에서 제안한 방법은 기존 방안보다 정밀하고, 사양이 다른 인공위성 레이저추적 시스템에도 쉽게 적용할 수 있다. 현재 전 세계 인공위성 레이저추적 시스템은 자동화 기술 개발에 집중적으로 연구하고 있는 추세이므로 본 연구결과는 인공위성 레이저 자동추적 분야에 그 활용도는 매우 크다고 할 수 있으며, 향후 세종 인공위성 레이저추적 시스템에도 적용 가능하리라 기대된다.

SLR (Satellite Laser Ranging) system measures the round trip flight time of ultra-short laser pulses to satellites to provide the information of the distance to satellites and it is the most accurate system among the systems determining orbits of satellites currently available. Automated signal acquisition for satellite laser ranging is based on the correlation detection using time-of-arrivals of a lot of pulses returned from satellites. It requires the selection of the correlation parameter and the frame time so that the true signal is distinguished from background noises with the specified signal detection and false alarm probabilities. In this study, the new method is proposed to select these parameters using the conditional equation derived from four characteristics of signal detection and false alarm probabilities. Additionally the conditional equation is expanded to analyze how signal and noise count rate have effect on these parameters selection. It also can be shown that this method gives more accurate solutions and is more powerful for the solution analysis than the existing method.

별은 저온 고밀도의 분자운에서 중력수축으로 형성된다. 중력수축으로 형성된 원시성(protostars)은 초기에 분자운 깊이 존재하며 강한 양축분출(bipolar outflows) 현상을 나타낸다. 원시성 주위를 둘러싸고 있는 구조(circumstellar envelopes)의 물질들은 이러한 양축분출로 흩어지거나 중심의 원시성으로 강착되어 소멸된다. 그리고, 원시성 주위에는 원반(circumstellar disks)이 형성되는데, 이 구조(protoplanetary disks)가 장차 행성계로 진화하게 된다. 이렇듯 별과 행성이 탄생하는 영역은 저온 고밀도이며 그 크기가 ~100 au로 작다. 따라서, 전파간섭계가 주 관측 수단이 된다. 본인의 연구 그룹에서는 세계 최대의 관측기기인 Atacama Large Millimeter/submillimeter Array (ALMA)를 주로 이용하여 별과 행성의 탄생에 관한 근원적인 의문들에 도전하게 된다. 예를 들어, 자기장과 난류가 별이 탄생하는 데 미치는 영향, 원시성 원반 형성과 진화에 미치는 자기장의 영향, 별 탄생 과정에서 먼지 알갱이들이 성장하는 시기와 크기, 원시성 원반에서 행성이 만들어지는 기작 등, 기기의 발달로 최근에야 관측연구가 가능하게 된, 흥미진진한 연구주제들이 다양하다. 연구를 수행함에 있어 필요에 따라, 다른 파장대의 관측자료 또는 전파단일경의 관측자료도 이용할 수 있는 기회가 많이 있을 것이다.

Observation cosmology (working with Yong-Seon Song): The recent progress in understanding the universe, and the massive astronomical data sets from planned surveys, provide unique opportunities to test fundamental laws of physics on cosmic scales. These lead us to new frontiers exploring the origin and fate of the Universe, the detection of invisible dark matter, and the nature of dark energy or gravity beyond Einstein. The next generation of deep wide-field surveys provide a fertile ground for expanding our knowledge and addressing cosmological questions. The Cosmology group at KASI is engaged in several of these major cosmological endeavors, such as the premier spectros wide field survey of the Dark Energy Spectros Instrument, the premier imaging wide field survey of Large Synoptic Survey Telescope, and the unprecedently deep and high resolution Giant Magellan Telescope. Their astronomical data will not only lead to a deeper understanding of our Universe, but deliver new, unexpected discoveries that expand our science framework. We research on critical questions about the Universe beyond present knowledge: 1) Initial Seeds – beyond the simplest model of early universe inflation, 2) Dark Matter – beyond the invisibility of dark matter, and 3) Dark Energy – beyond Einstein's gravity and vanishing vacuum energy.

적외선 관측기기 개발 및 이를 활용한 적외선 은하 생성의 기원과 역사 연구 

우주에서 활발한 별생성 활동을 보이는 은하들 대부분은 "obscured"되어 있기 때문에, 이러한 은하들의 생성과 진화를 연구하기 위해서는 적외선 관측기술에 대한 개발이 필요하다. 또한 먼 우주초기의 은하나 별빛들이 적색이동되어 관측되는 적외선 파장대는 지상 대기 및 열잡음에 의한 영향으로 지상 관측이 어려워 우주에서의 관측이 매우 효율적이기도 하다. 광학, 광기계, 자료 및 신호 처리 등 극한 우주환경을 견딜 수 있는 극미광 적외선 우주 관측 기술을 습득하여, 적외선 은하를 관측하기 위해 최적화된 다양한 영상/분광 타입의 적외선 관측 기기를 연구 개발하고자 한다. 개발된 적외선 기기를 활용한 적외선 은하 관측으로 그 은하들의 특성을 이해하기 위한 천체 물리학적인 이론과 분석 방법을 연구하고자 한다. 근적외선에서 부터 서브밀리 파장대에 이르는 다양한 적외선 파장대에 대한 다파장 관측 자료로 적외선 은하들의 생성 기원과 그 특성을 파악하여, 먼 우주에서 부터 현재에 이르는 우주 별생성 역사를 밝히고자 한다. 신입생들은 현재 개발이 진행 중이거나 계획 중인 적외선 우주망원경 개발 프로젝트에 참여하여 기기의 주요 파트들을 개발할 기회를 가질 수 있으며, 국외 협력 기관들과의 연구/개발 협력 기회도 주어질 예정이다. 아울러, AKARI, Herschel 등 국외 우주 망원경 및 국내 우주망원경인 MIRIS, NISS 등의 기존/예정 우주 관측 자료 뿐만이 아니고, 관측된 적외선 은하의 다파장 특성을 파악하기 위한 가시광 (KMTNet, 중대형 망원경), 서브밀리 (JCMT 및 ALMA) 등 후속 관측으로 얻은 자료들을 제안/분석하고 연구할 계획이다.

However, the recent joint analysis of BICEP2/Keck Array and Planck data has revealed that the first detection of CMB B-modes is only achieved when Galactic dust polarization is accurately modeled and separated from the CMB polarization data.

The successful candidate will be part of an international team to work on developing a self-consistent model of Galactic dust polarization by linking grain alignment to dust properties and local physical conditions of the interstellar medium. An important goal of this project is to apply the self-consistent polarization model to constrain the physics of the early universe with the CMB polarization as well as the physics of the interstellar medium. Students will be trained to master a wide range of research skills, including analytical and theoretical ability, numerical modeling and computational simulations.

Origin of solar type II radio bursts: 

Solar type II radio burst has been known as a signature of coronal shock wave but it's origin has not been fully understood. To understand the nature of the type II burst, solar physicists seek to working on solar electromagnetic and radiative processes of solar eruption such as flares and coronal mass ejections. Radio observations provide important diagnostics complementary to EUV, soft X-rays, hard X-rays, and gamma-rays, therefore solar observations based on advanced radio instruments such as LOFAR can lead understanding the physics of the radio emission. This is the main purpose of the project.

은하단 및 은하의 형성과 진화 (Galaxy clusters and galaxy formation and evolution)

 ▶ 연구목적: 은하단(galaxy cluster)은 우주에서 중력적으로 안정된 가장 큰 천체 (the largest relaxed, virialized system in the Universe)로 알려져 있다. 나아가 초은하단을 형성하지만 초은하단은 중력적으로 안정된 상태가 아니다. 또한 이런 은하단은 10-100배 정도 규모가 작은 은하군들의 병합으로 형성되는 것으로 알려지고 있다. 하지만, 우주의 탄생 이후 언제 은하군/은하단이 처음 만들어져서 어떻게 현재 우주의 거대 구조를 형성하였는지에 대한 시나리오는 아직 논쟁 중이다. 특히, 은하단의 형성과 진화는 우주의 진화(즉, 별생성 역사)와 밀접한 연관이 있음을 많은 관측적인 결과들이 말해 주고 있다. 이 연구의 목적은 은하단의 물질 분포 및 운동학적인 상태와 멤버 은하들의 상호 연관성 등을 우주의 나이로 분리하여 분석함으로써, 우주 거대 구조의 성장을 이해하는 것과 함께 다양한 은하단 환경이 멤버 은하의 진화에 미치는 영향을 이해하는 것이다.

 ▶ 연구방법: 은하단은 암흑 물질 (DM; Dark Matter), 은하간 물질 (ICM: Intra-cluster Medium), 멤버 은하로 이루어져 있다. 특히, 가장 밝고 무거운 특별한 은하(BCG; Brightest Cluster Galaxy)는 주로 은하단의 중심에 위치하며 우주의 거대구조와 (즉, 은하단 환경) 연계한 은하의 형성과 진화를 이해하는데 최적의 연구 대상이다. 이 연구에서는 관측 자료와 시뮬레이션 자료를 비교 분석하는 독자적인 방법을 개발할 것이다: 1) 관측 자료를 활용한 DM, ICM, 그리고 멤버 은하들의 총체적인 분포를 시뮬레이션 결과와 비교, 2) 은하단의 운동학적인 상태 그리고 진화 단계에 따른 BCG의 특성 비교를 통한 우주의 거대구조와 은하의 상호 관계 분석.

 ▶ 기대결과: 아래의 질문들에 대한 답을 찾아서 결과적으로 은하단의 형성과 진화를 이해하고, 은하단의 진화가 BCG 및 멤버 은하의 진화에 미치는 영향을 이해한다.

   - 은하단의 진화 단계에 따라서 은하단의 암흑물질 분포와 바리온 물질의 분포는 어떻게 다른가?

   - 은하단의 구조 및 운동학적인 특성이 BCG 및 멤버 은하의 별생성 역사에 어떤 영향을 주는가?  

   - BCG의 별생성 (star formation) 및 질량 증가 (mass assembly) 시나리오는?

별은 저온 고밀도의 분자운에서 중력수축으로 형성된다. 중력수축으로 형성된 원시성(protostars)은 초기에 분자운 깊이 존재하며 강한 양축분출(bipolar outflows) 현상을 나타낸다. 원시성 주위를 둘러싸고 있는 구조(circumstellar envelopes)의 많은 물질들은 이러한 양축분출로 흩어지거나 중심의 원시성으로 강착되어 소멸된다. 그리고, 원시성 주위에는 원반(circumstellar disks)이 형성되는데, 이 구조(protoplanetary disks)가 장차 행성계로 진화하게 된다. 이렇듯 별과 행성이 탄생하는 영역은 저온 고밀도이며 그 크기가 ~100 au로 작다. 따라서, 전파간섭계가 주 관측 수단이 된다. 본인의 연구 그룹에서는 세계 최대의 관측기기인 Atacama Large Millimeter/submillimeter Array (ALMA)를 주로 이용하여 별과 행성의 탄생에 관한 근원적인 의문들에 도전하게 된다. 예를 들어, 자기장과 난류가 별이 탄생하는 데 미치는 영향, 원시성 원반 형성과 진화에 미치는 자기장의 영향, 별 탄생 과정에서 먼지 알갱이들이 성장하는 시기와 크기, 원시성 원반에서 행성이 만들어지는 기작 등, 기기의 발달로 최근에야 관측연구가 가능하게 된, 흥미진진한 많은 연구주제들이 있다. 연구를 수행함에 있어 필요에 따라, 다른 파장대의 관측자료 또는 전파단일경의 관측자료도 이용할 수 있는 많은 기회가 있을 것이다.

V. KASI and CRESS
As the national research institute for astronomy since 1974, KASI has carried out research activities, especially by developing, establishing, and operating medium- and large-sized observational facilities and instruments and has laid the foundation for the advance of science. Solidifying scientific capabilities in research and on telescopes, KASI undertakes its efforts toward a higher level of global network of research cooperation. The three research divisions (Optical Astronomy, Radio Astronomy and Space Science) and the three research centers (Center for Large Telescope, Center for Theoretical Astronomy, Center for SMEs Partnership) have been newly set up, securing spontaneous ideas and each research project and enhancing the cooperation and the flexibility of the researchers.

KASI space weather group deals with scientific investigations of the Sun-Earth connection, thus studying the solar activity and the physics of Earth’s magnetosphere, ionosphere, and upper atmosphere by applying experimental and theoretical methods and numerical simulations. Especially, the part of ionosphere/upper atmosphere has focused on the ionospheric/thermospheric/mesospheric variations by solar activity and space environment changes and on the ionospheric irregularities.

KASI planetary science group is one of leading research institutes in South Korea for Korean lunar exploration mission. For supporting this challenging space mission, KASI is developing engineering models of ting-edge space payloads including near-infrared spectrometer, gamma-ray and neutron spectrometer. With these payloads, KASI is investigating the presence of water ice on the Moon and physical properties on the surface of airless body including lunar chronology, space weathering and lunar cratering.

The Centre for Research in Earth and Space Science (CRESS) is an interdisciplinary research unit in Lassonde School of Engineering at York University. The current areas of research cover a broad range of topics in earth and space science, from geodynamics to the study of the earth's troposphere, stratosphere, mesosphere and thermosphere, and the earth's plasma environment. It also includes research on planetary atmospheres, on stars (including the sun), and on the interplanetary medium. CRESS is involved in numerous Canadian, NASA, and international spaceflight projects including the NASA OSIRIS-REx mission for planetary exploration and Phoenix mission to Mars. CRESS involves faculty from the Departments of Chemistry, Computer Science, Earth and Space Science and Engineering and Physics & Astronomy. Some current highlights include: CSA Group Achievement Award for leadership in the Wind Imaging Interferometer project; M. Richer, graduate student of Professor McCall, nominated for the doctoral thesis prize and awarded the Plaskett medal of the Canadian Astronomical Society for 1995; NASA Group Achievement Award for contributions to the Upper Atmosphere Research Satellite mission; OMEE Award for Excellence in Research and Technology Development to professors Hastie, Shepson and McConnell; Professor Marshall McCall discovers two new galaxies located nearby to our own galaxy, the Milky way. An award from the Canadian Foundation for Innovation to Professor McConnell has provided high performance computers for atmospheric modelling of air quality, and a laboratory on the roof of the Petrie Science and Engineering Building. A CFI award to Professor Quine has provided space test facilities; a vibration test facility, and a thermal vacuum facility.

In 2015, CRESS (Professor Michael Daly, York Research Chair in Planetary Science) receives more than .3 million in funding to build a Canadian Planetary Simulator (CAPS) facility. The Canadian Planetary Simulator will allow the simulation and investigation of extreme terrestrial and other planetary environments as well as the development and testing of instruments suited to these environments. The simulator is the only one of its kind known - a combination of capable integrated instruments with a capable environmental simulator. It will allow Canadian universities to lead high profile research in planetary and instrument science and provide Canadian companies with competitive advantages in the development of instrumentation. Daly will lead a team of scientists from York University, as well as collaborators from eight companies and 10 other universities on the project.

Also, the members at the CRESS (Professors Tom McElroy and Regina Lee) receive more than .68 million in funding to establish a state-of-the-art research facility for designing, building, characterizing and operating instruments and payloads for sub-orbital missions. The facility will support end-to-end mission development for cost-effective, orbital and sub-orbital platforms: nanosatellites, sub-orbital rockets, high-altitude balloons and airplanes. The facility will comprise: (1) a micro-fabrication laboratory optimized for the production of Microelectromechanical systems (MEMS) payloads; (2) a payload calibration and flight test-bed for the purposes of systems integration and space-qualification; and (3) a mission operations centre for real-time data analysis, satellite tracking and communications.
