Constraining primordial black hole abundance with the Galactic 511 keV line
William DeRocco, Peter W. Graham
Models in which dark matter consists entirely of primordial black holes (PBHs) with masses around g are currently unconstrained. However, if PBHs are a component of the G…

Supernova signals of light dark matter
William DeRocco, Peter W. Graham, Daniel Kasen +2
Dark matter direct detection experiments have poor sensitivity to a galactic population of dark matter with mass below the GeV scale. However, such dark matter can be produced copi…

Observable signatures of dark photons from supernovae
William DeRocco, Peter W. Graham, Daniel Kasen +2
A dark photon is a well-motivated new particle which, as a component of an associated dark sector, could explain dark matter. One strong limit on dark photons arises from excessive…
