Black holes and gravitational waves from phase transitions in realistic models
Marek Lewicki, Piotr Toczek, Ville Vaskonen
We study realistic models predicting primordial black hole (PBH) formation from density fluctuations generated in a first-order phase transition. We show that the second-order corr…

Black holes and gravitational waves from slow phase transitions
Marek Lewicki, Piotr Toczek, Ville Vaskonen
Slow first-order phase transitions generate large inhomogeneities that can lead to the formation of primordial black holes (PBHs). We show that the gravitational wave (GW) spectrum…

Primordial black holes from strong first-order phase transitions
Marek Lewicki, Piotr Toczek, Ville Vaskonen
We study the formation of primordial black holes (PBHs) in strongly supercooled first-order phase transitions. The mechanism is based on the presence of remnants dominated by the f…
