Abstract:

Time-domain transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Earlier theoretical works focused mainly on the TDEs in otherwise quiescent galaxies. TDE studies are developing and recent observations suggest more complex picture than expected. In this talk, I will introduce the progress in the study of TDEs, particularly those associated with active galaxies, and more interestingly the stellar disruption by supermassive black hole binaries. In addition, the results from our on-going X-ray and radio follow-up observations of TDE candidates will be shown. I will end with the summary of challenges in distinguishing various types of nuclear transients in future studies. 


Bio:

Prof. Shu's research focuses on transients, AGN physics and high-redshift galaxies. He obtained PhD in astrophysics at USTC on 2010, and then spent 3 years as postdoc and associate researcher in USTC. Since 2013, he moved to CEA/Saclay as a postdoctoral researcher for about two years. After that, he joined Anhui Normal University at Department of Physics in 2015. Till now, Prof. Shu published more than 80 referred papers with total citations of >3000 and H-index 27.
