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 $\sim 100 km s^{- 1}$ can be tested with dwarf galaxy observations. We ana…

Probing Atomic Dark Matter with Stellar Streams in Milky Way-Mass Galaxies

Lucas S. Mandacarú Guerra, Stephanie O'Neil, Mariangela Lisanti +7

We present the first detailed analysis of the effects of dissipative dark matter on stellar streams. As a concrete example, we generate a cosmological hydrodynamic zoom-in simulati…
