Exoplanets from BOAO

Exoplanets from BOAO The current number of confirmed exoplanets is close to 6,000, many more candidates waiting to be confirmed. Discovery of exoplanets and characterization of their physical properties seem trivial, but they are not. I will introduce how we find and study exoplanets with Bohyunsan Observatory Echelle Spectrograph (BOES) and SPECtrophotometer for TRansmission spectroscopy […]

Lyα as a promising probe of the Reionization Era

Lyα as a promising probe of the Reionization Era Lyman-alpha (Lyα) emission and absorption features from galaxies beyond redshift 6 offer crucial insights into the epoch of reionization. Recent observations by the James Webb Space Telescope (JWST) have unveiled numerous intriguing cases that challenge our theoretical understanding of the intergalactic medium (IGM) Lyα opacity. In […]

Probing parity violation in the early Universe using galaxy spins

Title : Probing parity violation in the early Universe using galaxy spins   Abstract : Recent 3-7σ detections of parity asymmetry in the observed galaxy distribution have spurred interest in searching for potential signals of primordial parity violation. In this talk, I will explore the possibility of detecting parity-violation in primordial vector fossils using late-time galaxy spins. […]

Electromagnetic signatures from binary mergers: from gamma-ray bursts to kilonova

Electromagnetic signatures from binary mergers: from gamma-ray bursts to kilonova The advent of multi-messenger astronomy, which combines gravitational waves with electromagnetic counterparts, has dramatically enhanced our understanding of the universe's most extreme events. Electromagnetic emissions from binary mergers—ranging from gamma-ray bursts (GRBs) to kilonovae—provide crucial insights into these phenomena. GRBs offer a glimpse into the […]

Study on the Physical Properties of Asteroids in the Era of Large Survey

Study on the Physical Properties of Asteroids in the Era of Large Survey Asteroids are considered among the most primitive celestial bodies in our solar system and are crucial for understanding the origin and formation processes of the solar system. Furthermore, the significance of asteroids has been increasingly recognized, both in terms of planetary defense […]

Magnetized Plasma Processes in the Universe

Magnetized Plasma Processes in the Universe Magnetized plasmas are ubiquitous in the Universe and are important because many of the events therein are governed by their dynamics. Understanding their nature is thus crucial in various contexts including astrophysics, space, and nuclear fusion. In this talk, I will present an overview of magnetized plasmas and their […]

Opening a New Horizon with a Korea-led L4 Mission: Vision and Plan

Opening a New Horizon with a Korea-led L4 Mission: Vision and Plan     The Sun-Earth Lagrange point L4 is considered as one of the unique places where the solar activity and heliospheric environment can be observed in a continuous and comprehensive manner. The L4 mission affords a clear and wide-angle view of the Sun-Earth […]

Space Industry; Past, Present & Future

우주산업의 과거, 현재 그리고 미래   1992년 8월 10일에 발사된 우리별 1호는 이미 30년이 넘는 시간동안 지구를 돌면서 동면해 있습니다. 한국이 발사한 최초의 위성으로 자리매김한 우리별 1호는 그 당시 많은 후배들에게 영감을 주었으며, 대한민국의 우주개발 1세대를 열었습니다. 2021년 10월 21일에 처녀발사를 한 누리호 발사체 (KSLV-II) 는 궤도 안착에는 실패하였지만, 2022년 6월 21일에 두번째 발사에서 성공적인 […]
