Description

I will discuss how to calculate the PBH abundance and mass distribution starting from the inflationary potential, taking into account stochastic effects and using the compaction function. We determine the radial profiles directly from stochastic calculation, and do not assume Gaussianity. I will outline progress and how to address the remaining open issues.
