Key Details
Minimal ingredients for PBH formation already present in supersymmetry
New long-range scalar forces can facilitate early structure growth
PBHs could explain all dark matter in unconstrained mass range
Orphan kilonovae with fast radio bursts would indicate PBH dark matter
Gravitational waves probe PBH formation on microscopic scales

Primordial black hole formation and detection
This paper reviews recent ideas for how primordial black holes could have formed in the early universe, and strategies to detect them. Some ideas involve minimal extensions to known physics like supersymmetry, while others rely on new long-range forces. Signatures to detect primordial black holes range from gravitational waves, to effects on structure growth, neutron star destruction, and orphan kilonovae with fast radio bursts.
