Why the mean mass of primordial black hole distribution is close to 10<i>M</i><sub>⊙</sub>
A. Dolgov, K. Postnov
Abstract
It is shown that a mechanism of PBH formation from high-baryon bubbles with log-normal mass spectrum naturally leads to the central mass of the PBH distribution close to ten solar masses independently of the model details. This result is in good agreement with observations.
