Prof. Dai’s research interests are high energy astrophysics, black hole accretion disks and jets, tidal disruption event, compact objecon and general relativistic simulations. Prof. Dai got his bachelor from the Hong Kong University of Science and Technology in 2005 and the PhD from the Stanford University in Physics in 2012. In April 2019, Prof. Dai joined the University of Hong Kong as an assistant professor.

报告摘要:

主要会讲述宇宙中发生于一些星系中心的电磁辐射爆发事件:恒星被超大质量黑洞撕裂-它的观测和研究现状,并阐述作者对此的学术观点:恒星潮汐瓦解事件的多波段辐射,以及它们在观测表现上的多样性,来自于恒星撕裂后的残骸向黑洞的超爱丁顿吸积导致。

Tidal disruption events (TDEs), in which stars are torn apart by the tidal force from massive black holes, provide good opportunities for probing massive black hole demographics. Furthermore, TDEs are ideal laboratories for studying black hole accretion and jet physics. In this talk, I will first give an introduction to the TDE physics, followed by a summary of current observations. Then I will focus on our latest work on understanding the diversity, evolution and demographics of TDEs.
