Xiamen-Cardiff Seminar

How big are quasars?

Speaker: Mouyuan Sun (Xiamen University)
Date: Friday 26 November 2021
Time: 9:30
Venue: Zoom

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 spatially 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.
