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…
511 keV Gamma Ray Echo from Particle Decays in Supernovae
Garv Chauhan, Cecilia Lunardini
The formation of a hot and dense core in a core-collapse supernova (SN) can produce massive Beyond Standard Model (BSM) particles. These particles can decay in the stellar envelope…
LIQUIDating the Gallium Anomaly
Garv Chauhan, Patrick Huber
The gallium anomaly has a global significance of greater than . Most viable BSM solutions quickly run into strong tensions with reactor and solar neutrino data. We propose to…
Neutron Stars as a Probe of Cosmic Neutrino Background
Garv Chauhan
The Cosmic Neutrino Background (CB) constitutes the last observable prediction of the standard cosmological model, which has yet to be detected directly. In this work, we show…
Low-Energy Supernovae Bounds on Sterile Neutrinos
Garv Chauhan, Shunsaku Horiuchi, Patrick Huber +1
Sterile neutrinos can be produced through mixing with active neutrinos in the hot, dense core of a core-collapse supernova (SN). The standard bounds on the active-sterile mixing ($…
Supernova Gamma-Ray Constraints from Heavy Sterile Neutrino Decays
Garv Chauhan, R. Andrew Gustafson, Ian M. Shoemaker
Heavy sterile neutrinos can be produced in core-collapse supernovae (CCSNe), which are superb particle generators because of their high densities and temperatures. If the sterile n…
