Since the initial discovery of gravitational-waves from merging black holes,the LIGO Scientific Collaboration together with Virgo and KAGRA have published90 gravitational-wave observations of compact binary mergers in theGravitational-Wave Transient Catalog papers. In this work, we carry out aninvestigation of isolated binary evolution formation channel, comparingpredictions of the gravitational-wave population from the StarTrack syntheticuniverse simulations to the observed population. We construct, apply, andprovide parametric and non-parametric models for the likelihood function of thefull set of astrophysical parameters of each event in the Gravitational-WaveTransient Catalogs, including truncated multivariate normal distributionsnormalized on a bounded interval, demonstrated in our prior work. We presentour findings for the formation parameters for the isolated binary evolutionformation channel for compact objects. Our preliminary results demonstrate thebenefits of a multi-dimensional analysis which is sensitive to theinterdependence of the predicted detection population on many formationparameters. Our essential contribution is therefore a method for carrying outsuch an analysis efficiently. We discuss potential sources of bias as we alsopresent the properties of our best binary evolution models, which areconsistent with unrestricted stellar mass loss due to winds, high mass andangular momentum loss to ejected portions of a common envelope, and substantialblack hole supernova recoil kicks. We conclude with a discussion of the impactof these activities for gravitational-wave and multi-messenger astronomy.
