Mapping the Distorted Dark Matter Distribution of the LMC–SMC System Prior to Milky Way Infall with Basis Function Expansions

The SMC orbits within the LMC’s dark matter (DM) halo in a ∼1:10 mass-ratio encounter. The LMC–Milky Way (MW) interaction is also ∼1:10, and is expected to perturb the MW’s DM distribution. However, no framework exists to quantify the severity of these perturbations over multiple pericenters and lon...
