Investigation of galaxy formation under inelastic two-component dark matter via cosmological zoom-in simulations of Milky Way-like systems

ORAL

Abstract

We present the first cosmological zoom-in simulations involving inelastic two-component dark matter and IllustrisTNG baryonic physics. We study the formation and evolution of a Milky Way-like system, including density profiles, rotation curves, gravitational potential, and star formation history. We discuss the interplay between inelastic DM processes and baryonic effects, and compare to earlier studies involving elastic SIDM.
