Abstract
Abstract We present results on the mass, spin, and redshift distributions with phenomenological population models using the 10 binary black hole (BBH) mergers detected in the first and second observing runs completed by Advanced LIGO and Advanced Virgo. We constrain properties of the BBH mass spectrum using models with a range of parameterizations of the BBH mass and spin distributions. We find that the mass distribution of the more massive BH in such binaries is well approximated by models with no more than 1% of BHs more massive than 45 M ⊙ and a power-law index of α = 1.3 − 1.7 + 1.4 (90% credibility). We also show that BBHs are unlikely to be composed of BHs with large spins aligned to…
