Mergers Matter: Gravothermal Collapse in Dwarf Halos with Self-Interacting Dark Matter
Maya Silverman, Abdelaziz Hussein, Arpit Arora +8
Self-Interacting Dark Matter (SIDM) models with large cross sections at relative velocities below can be tested with dwarf galaxy observations. We ana…

Galactic Amnesia: The Information Washout of the Milky Way Merger History
Lina Necib, Dylan Folsom, Elliot Y. Davies +2
The merger history of a galaxy leaves imprints on its present-day stellar chemodynamics, yet dynamical processes progressively erase this record. We ask: how far back in time, and…

Set the Night on FIRE: Building an Empirical Local Dark Matter Velocity Distribution
Xiuyuan Zhang, Andreas Thoyas, Lina Necib +2
The majority of terrestrial direct detection experiments for Dark Matter (DM) rely on the Standard Halo Model (SHM), which assumes the local DM velocity distribution follows a Maxw…
