Title: How big are quasars?

Speaker: Mouyuan Sun

Institute: Xiamen University

Host: Cardiff U-XMU Joint Physics Seminar

Time: 17:30-18:30, Thursday, November, 26

Location: Zoom (Meeting ID: 922 8539 2843, PWD: 168617)


Abstract:

Distant quasars are powered by accretion onto supermassive black holes (SMBHs). Understanding this fundamental astrophysical process is vital for better constraining the cosmic mass growth history of SMBHs and the (possible) co-evolution between SMBHs and their host galaxies. So far, this SMBH accretion process can be resolved only in the time domain. In this talk, I'll briefly discuss how we use the time-domain measurements of quasar sizes to probe the fundamental SMBH accretion process.


Bio:

Mouyuan Sun obtained his Ph.D. from Xiamen University. During 2013-2015, he was a long-term visiting student at Penn State University. Then, he spent three years at the University of Science and Technology of China as a postdoc and a research associate. He joined the Department of Astronomy at Xiamen University in July 2019.

His research interests are: active galactic nuclei, time-domain astronomy, and high-energy astrophysical phenomenon.
