Abstract (from CDS):

The probability number distribution function of binary black hole mergers observed by LIGO/Virgo O3a has double peaks as a function of chirp mass Mchirp, total mass Mtotal, primary black hole mass M1, and secondary one M2, respectively. The larger chirp mass peak is at Mchirp~= 30 M☉. The distribution of M2 versus M1 follows the relation of M2~= 0.7M1. For initial mass functions of Population III stars in the form of f(M) ∝ M–α, population synthesis numerical simulations with 0 <= α <= 1.5 are consistent with O3a data for Mchirp >= 20 M☉. The distribution of M2 versus M1 for simulation data also agrees with M2 ~= 0.7M1 relation of O3a data.
