Description
This talk concerns a novel study to obtain the initial spin of the primordial black holes created during a first-order phase transition due to delayed false vacuum decay. Remaining within the parameter space consistent with observational bounds, the abundance and the initial spin of the primordial black holes are expressed as functions of the phase transition parameters. The abundance of the primordial black holes is extremely sensitive to the phase transition parameters. It was also found that the initial spin weakly depends on all parameters except the transition temperature.
