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.
