Description
I shall present some details how to compute the PBH merger rate and show results of a dedicated simulation of PBH clustering at the early Universe. I apply the results to fit LIGO data and derive constraints on PBH abundance. I discuss the possibility that LIGO has observed two populations of black holes, astrophysical and primordial.
