Title: Accretion Disk and Corona around Black Holes

Speaker: 劉碧芳, 研究員 (百人計劃), 中科院國家bet体育万博臺

Time & Place: 週四, 2019.7.18下午2:30-4:30, 物理樓552

Abstract: Accretion is one of the most fundamental processes for understanding a variety of active phenomena in black holes. A brief overview of the observational properties in black holes and physical understanding will be introduced. The two-phase accretion flows, i.e. an accretion disk sandwiched in corona, will be described in detail. By studying the physical processes in these accretion flows, in particular, the mass and energy exchange between the disk and the corona, we find they are a promising scenario to reveal the nature of spectra and transition in black holes.
