I will discuss recent high-resolution N-body simulations of self-interacting dark matter and their implications for the latest astrophysical observations of diverse galactic systems. In particular, I will highlight the novel signatures of gravothermal collapse in dark matter halos and explore their detection possibilities through observations of strong lensing systems, stellar streams, and supermassive black holes.
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.
