ABSTRACT
I will discuss recent high-resolution cosmological N-body simulations of self-interacting dark matter and their implications for astrophysical observations of diverse galactic systems. In particular, I will highlight novel signatures of gravothermal collapse in dark matter halos and explore their potential detection through strong lensing systems, stellar streams, and supermassive black holes.
BIOGRAPHY
Yu earned his PhD from the University of Maryland, College Park, in 2007. He then worked as a postdoctoral researcher at the University of California, Irvine, and the University of Michigan. Since 2013, he has been a faculty member at the University of California, Riverside, starting as an assistant professor before advancing to associate professor and now full professor.
Yu's research focuses on astrophysical probes of dark matter, the small-scale structure of the Universe, and the origin of supermassive black holes. He has published over 90 research papers, with more than 10,000 citations. He received the Outstanding Young Researcher Award from the International Organization of Chinese Physicists and Astronomers and was also awarded the Hellman Fellowship.
