New ideas on the formation and astrophysical detection of primordial black holes
Marcos M. Flores, Alexander Kusenko
Recently, a number of novel scenarios for primordial black hole (PBH) formation have been discovered. Some of them require very minimal new physics, some others require no new ingr…
Revisiting formation of primordial black holes in a supercooled first-order phase transition
Marcos M. Flores, Alexander Kusenko, Misao Sasaki
We reexamine production of primordial black holes in a supercooled phase transition. While a mere overdensity associated with a surviving false-vacuum patch does not imply formatio…
Spins of primordial black holes formed in different cosmological scenarios
Marcos M. Flores, Alexander Kusenko
Primordial black holes (PBHs) could account for all or part of dark matter, as well as for some LIGO events. We discuss the spins of primordial black holes produced in different co…
Primordial black holes from long-range scalar forces and scalar radiative cooling
Marcos M. Flores, Alexander Kusenko
We describe a new scenario for the formation of primordial black holes (PBHs). In the early Universe, the long-range forces mediated by the scalar fields can lead to formation of h…
