报告摘要：Both young stars in the central parsec of our Galaxy and super-solar metallicity as found in parsec-scale of broad emission lines of QSOs suggest the presence of stars very close to SMBHs. The stellar process in this extreme environments should be much different from the isolated stars in large-scale galaxy. The tidal disruption events, future space GW detection on extreme mass-ratio inspirals and possible stellar-mass BH merger events in AGN disk will shed light on the unresolved nuclear stellar process in distant galaxies. I will present and discuss the following contents: nuclear stellar process in our Galaxy center; metal enrichment in nuclear region of AGNs; dynamics of stellar-mass BH binary in AGN disk and possible GW features; the possible nuclear stellar process in compact little red dots.

主讲人简介：Professor in Department of Astronomy in Huazhong University of Science and Technology. I mainly work on AGN physics. In last several years, I try to use multimenssenger to explore the parsec-scale nuclear stellar process near SMBHs in order to understand coevolution of SMBH and galaxy.
