Abstract

“The LIGO and Virgo gravitational-wave interferometers are expected to deliver hundreds of detections in a few years. In a few decades, the number of events will be in the millions. As gravitational-wave astronomy enters its data-driven regime, interest is quickly shifting from determining the parameters of single events to inferring those describing the entire population of sources. These contain precious insights into the demographics of progenitor systems and the physics guiding stellar evolution. I summarize and report progress on the applications of novel statistical techniques to mine gravitational-wave catalogs and directly infer posterior probability distributions of the population parameters. In particular, I present (i) results from Gaussian-process emulators trained on large banks of compact-binary population-synthesis simulations and (ii) the applications neural-network classifiers to model LIGO/Virgo selection effects”.
