Spins of primordial black holes formed with a soft equation of state
Abstract We investigate the probability distribution of the spins of primordial black holes (PBHs) formed in the universe dominated by a perfect fluid with the linear equation of state p = wρ , where p and ρ are the pressure and energy density of the fluid, respectively. We particularly focus …
