In this talk, I will discuss recent work on self-interacting dark matter and its implications within the context of the latest observations of galactic systems, as well as high-resolution N-body simulations of cosmic structure formation. I will highlight the novel signatures of gravothermal collapse in dark matter halos, which represent a unique prediction that arises if dark matter possesses strong self-interactions.    

Bio: Yu earned his PhD degree from the University of Maryland, College Park in 2007. After completing his PhD, Yu worked as a postdoctoral researcher at the University of California, Irvine, and the University of Michigan. Since 2013, Yu has been a faculty member at the University of California, Riverside. He started as an assistant professor and later became an associate professor. Currently, he holds a full professor position. In 2016, Yu received the Outstanding Young Researcher Award from the International Organization of Chinese Physicists and Astronomers. He was also a recipient of the Hellman fellowship. Yu has published over 70 research papers, accumulating more than 10,000 citations. His current research interests revolve around astrophysical probes of dark matter, numerical simulations of structure formation, and the origin of supermassive black holes.
