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…

Dark matter decay signals in cosmic filaments
Elena Pinetti, Evan Vienneau, Nassim Bozorgnia
Cosmic filaments form the backbone of the cosmic web, yet their properties and evolution remain uncertain. Using the EAGLE hydrodynamical simulations, we investigate the dark matte…
