  The Gallium Solar Neutrino Capture Cross Section Revisited

  Solar neutrino flux constraints from the legacy GALLEX/GNO and SAGE experiments continue to influence contemporary global analyses of neutrino properties. The constraints depend on the neutrino absorption cross sections for […]

  Searching for MeV-mass neutrinophilic Dark Matter with Large Scale Dark Matter Detectors

  The indirect detection of dark matter (DM) through its annihilation products is one of the primary strategies for DM detection. One of the least constrained classes of models is neutrinophilic […]

  Dark Matter-Powered Stars and the High-Redshift Tidal Disruption Event Rate

  Tidal disruption events (TDEs) result from stars being gravitationally-scattered into low angular momentum orbits around massive black holes. We show that the short lifetimes of massive Population III stars at […]

  Sterile Neutrino Dark Matter Gets Even Cooler

  We don’t yet know what makes up dark matter, but we do know that it doesn’t belong to the familiar particles of the Standard Model. One promising class of very well motivated dark matter candidates are dark neutral leptons, or “sterile neutrinos”.

  Dark Population Transfer Mechanism for Sterile Neutrino Dark Matter

  We present a mechanism for producing a cosmologically significant relic density of one or more sterile neutrinos. This scheme invokes two steps: First, a population of “heavy” sterile neutrinos is […]
