Light, asteroid-mass primordial black holes, with lifetimes in the range between hundreds to
several millions times the age of the Universe, are well-motivated candidates for the …

We study the possibility of production of primordial black holes (PBHs) from bubble
collisions during a first-order phase transition. While typical colliding bubbles are small and …

The indirect detection of dark matter particles with mass below the GeV scale has recently
received significant attention. Future space-borne gamma-ray telescopes, including All-Sky …

We outline the science opportunities in the areas of searches for dark matter and new
physics offered by a proposed future MeV gamma-ray telescope, the Galactic Explorer with a …
