Title: Why Dark Matter May Have Self-Interactions

Speaker: Haibo Yu

Abstract: Dark  matter makes up most of the  matter in the Universe, yet its fundamental nature remains unknown. In this talk, I will present
recent high-resolution N-body simulations of  self-interacting  dark
matter and discuss their implications for a wide range of
astrophysical observations. I will highlight new signatures associated
with gravothermal collapse in  dark  matter halos and show how they  may be detected through observations of strong gravitational lensing,
stellar streams, and supermassive black holes, including the JWST
Little Red Dots. These studies open new avenues for uncovering the
particle physics of  dark  matter.
