Core-collapse universality for inelastic self-interacting dark matter halos
Evan Batteas, Alexander Brisebois, Maheen Hemani +6
We study the gravothermal collapse of inelastic dark matter halos with velocity-dependent elastic and dissipative self-interactions. Within the gravothermal fluid framework, we der…

Dark matter annihilation signals from the Large Magellanic Cloud and its impact on the Milky Way
Evan Vienneau, Evan Batteas, Addy J. Evans +3
We study the dark matter (DM) annihilation signals from the Large Magellanic Cloud (LMC) and the impact of the LMC on the DM annihilation signals from the Milky Way (MW) halo, usin…

Enhancements in velocity-dependent dark matter annihilation in Galactic subhalos
Odelia V. Hartl, Evan Vienneau, Evan Batteas +3
We examine velocity-dependent dark matter annihilation in subhalos using a sample of six Milky Way-like galaxies from the Aurgia simulation suite. We quantify the enhancement in th…
