안녕하십니까.

오는 수요일(11월 4일) 오후 4:00에 아래와 같이 2026년 하반기 정규 콜로키움이 진행될 예정입니다.

발표 후에는 연사와의 대화시간(5:00-5:40) 및 저녁 식사가 예정되어 있으니 많은 참여 부탁드립니다.

발표자: 우종학 교수 (Seoul National University)

호스트: 한정열

장소: 장영실홀 331-2 및 원격 연결

일시: 11월 4일 (수) 오후 4:00

접속주소: https://us06web.zoom.us/j/84840334355?pwd=3FUkcuaYwNQwscjoUSo3ulk6KPPo6x.1

교육학점: 천문연 소속 현장참석자의 경우 필수 0.5 학점 부여

제목: Unveiling the Central Engines of Active Galactic Nuclei through Time-Domain and Spatially Resolved Observations

초록: 

Mass accretion onto supermassive black holes plays a key role in galaxy evolution, driving black hole growth and feedback processes that affect the surrounding stars and gas over cosmic time. In this talk, I will discuss recent progress in understanding the central engines of active galactic nuclei (AGN), focusing on the physical properties and structure of the accretion disk and broad-line region. In particular, I will highlight recent results from reverberation mapping and spatially resolved gas kinematics, which provide complementary insights into the structure and dynamics of AGN. Finally, I will discuss future prospects for time-domain and high-angular-resolution studies using space- and ground-based facilities.
