|Title:||Self-Interacting Dark Matter (special seminar)|
|Speaker:||Prof. Hai-Bo Yu (University of California, Riverside)|
Astrophysical observations ranging from dwarf galaxies to galaxy clusters indicate that dark matter halos are much more diverse than predicted in the prevailing cold dark matter theory. In this talk, I will show that self-interacting dark matter can provide a unified solution to a number of long-standing puzzles in astronomy and astrophysics, including the diverse galaxy rotation curves, radial acceleration relation, dark matter distributions in Mike-Way satellite galaxies and density cores in galaxy clusters.
Dr. Haibo Yu is an assistant professor at the Department of Physics and Astronomy at University of California, Riverside. Before joining UCR, he was a postdoctoral researcher at UC Irvine and UMICH before he received his Ph.D. from University of Maryland in 2007. Dr. Yu's research is focused on theoretical particle physics and its interface with cosmology and astrophysics. He works on new physics beyond the Standard Model with emphasis on dark matter and collider phenomenology.
