Dark matter energy exchange in stars orbiting supermassive black holes
Stephan A. Meighen-Berger, R. Andrew Gustafson, Nicole F. Bell +3
Stars on tight orbits around the supermassive black hole at the Galactic Center pass through regions where the dark matter~(DM) density may be strongly enhanced. We compute the orb…
Self-Interaction and Galactic Magnetic Field Bounds on Millicharged Magnetic Monopole Dark Matter
Michael L. Graesser, R. Andrew Gustafson
A dark matter sector composed of magnetic monopoles of a dark U(1) symmetry having a small kinetic mixing with the Standard Model photon has a rich and interesting phenomenology. T…
The Dark Matter Diffused Supernova Neutrino Background
Garv Chauhan, R. Andrew Gustafson, Gonzalo Herrera +2
We consider neutrinos scattering off Milky Way dark matter and the impact of this scattering on supernovae neutrinos. This can take the form of attenuation on the initial flux of n…
Probing Dark Matter Interactions with Stellar Motion near Sagittarius A*
R. Andrew Gustafson, Ian M. Shoemaker, Volodymyr Takhistov
Stars orbiting Sgr A* at the Milky Way's center provide a unique laboratory to test gravity and dark matter (DM). We demonstrate that DM interactions in stellar interiors induce a…
Cosmic-Ray Cooling in Active Galactic Nuclei as a New Probe of Inelastic Dark Matter
R. Andrew Gustafson, Gonzalo Herrera, Mainak Mukhopadhyay +2
We present a novel way to probe inelastic dark matter using cosmic-ray (CR) cooling in active galactic nuclei (AGNs). Dark matter (DM) in the vicinity of supermassive black holes m…
