A Self-interacting Dark Matter Solution to the Extreme Diversity of Low-mass Halo Properties
The properties of low-mass dark matter (DM) halos appear to be remarkably diverse relative to cold, collisionless DM predictions, even in the presence of baryons. We show that self-interacting DM (SIDM) can simultaneously explain observations of halo diversity at two opposite extremes—the inner dens...
