Gravothermal Solutions of SIDM Halos: Mapping from Constant to Velocity-dependent Cross Section

The scale-free gravothermal fluid formalism has long proved effective in describing the evolution of self-interacting dark matter halos with a constant dark matter particle cross section. However, whether the gravothermal fluid solutions match numerical simulations for velocity-dependent cross-secti...
