Effects of Inelastic Two-Component Dark Matter in Subhalo Formation and Composition

The nature of dark matter remains one of the greatest outstanding problems

in fundamental physics. As we lie on the cusp of next-generation observatories,

there will soon be greater opportunity to probe the inner structure of low mass

halos with V_max ≲ 30 km s^-1. Astrophysical signatures of dark-sector physics

are expected to be found in such systems, but these effects must be disentangled

from those of baryonic feedback. By utilizing cosmological simulations with

state-of-the art baryonic feedback models, we explore the interplay between

baryonic feedback and inelastic dark matter models. We demonstrate the effects

of a simple inelastic dark matter model on a number of classical halo statistics

and how those results are altered by baryonic physics.
