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…
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 boosted inelastic dark matter from neutrino-emitting active galactic nuclei
R. Andrew Gustafson, Gonzalo Herrera, Mainak Mukhopadhyay +2
Cosmic rays may scatter off dark matter particles in active galactic nuclei, where both the densities of cosmic rays and dark matter are expected to be very large. These scattering…
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…
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…
Detecting Boosted Dark Photons with Gaseous Detectors
Michael L. Graesser, R. Andrew Gustafson, Kate Hildebrandt +2
We search for indirect signals of (keV) dark matter annihilating or decaying into (eV) dark photons. These dark photons will be highly boosted and have de…
