Velocity-dependent annihilation radiation from dark matter subhalos in cosmological simulations
Erin Piccirillo, Keagan Blanchette, Nassim Bozorgnia +4
We use the suite of Milky Way-like galaxies in the Auriga simulations to determine the contribution to annihilation radiation from dark matter subhalos in three velocity-dependent…
Dark matter annihilation and the Galactic Centre Excess
Robert J. J. Grand, Simon D. M. White
We compare the surface brightness profile and morphology of the Galactic Centre Excess (GCE) identified in wide-angle -ray maps from the Fermi-Large Area Telescope to dark matte…
Velocity-dependent J-factors for annihilation radiation from cosmological simulations
Erin Board, Nassim Bozorgnia, Louis E. Strigari +6
We determine the dark matter pair-wise relative velocity distribution in a set of Milky Way-like halos in the Auriga and APOSTLE simulations. Focusing on the smooth halo component,…
Numerical Simulations of Bubble-Induced Star Formation in Dwarf Irregular Galaxies with a Novel Stellar Feedback Scheme
Daisuke Kawata, Brad K. Gibson, David J. Barnes +2
To study the star formation and feedback mechanism, we simulate the evolution of an isolated dwarf irregular galaxy (dIrr) in a fixed dark matter halo, similar in size to WLM, usin…
