The LIGO and Virgo detectors have directly observed gravitational waves from mergers of
pairs of stellar-mass black holes, along with a smaller number of mergers involving neutron …

We report on the population properties of compact binary mergers inferred from gravitational-
wave observations of these systems during the first three LIGO-Virgo observing runs. The …

The second LIGO–Virgo catalog of gravitational-wave (GW) transients has more than
quadrupled the observational sample of binary black holes. We analyze this catalog using a …

The second LIGO/Virgo observing run (O2) spanned 9 months between 2016 November
and 2017 August, building on the first, 4-month run (O1) in 2015. The LIGO/Virgo …

Abstract Machine learning has emerged as a popular and powerful approach for solving
problems in astrophysics. We review applications of machine learning techniques for the …

We introduce the first complete nonparametric model for the astrophysical distribution of the
binary black hole (BBH) population. Constructed from basis splines, we use these models to …

We present the first systematic study of strong binary–single and binary–binary black hole
(BH) interactions with the inclusion of general relativity. By including general relativistic …

During its first four months of taking data, Advanced LIGO has detected gravitational waves
from two binary black hole mergers, GW150914 and GW151226, along with the statistically …

Gravitational-wave detections have revealed a previously unknown population of stellar
mass black holes with masses above 20 M⊙. These observations provide a new way to test …

We explore the ability of gravitational-wave detectors to extract the redshift distribution of
binary black hole (BBH) mergers. The evolution of the merger rate across redshifts 0< z≲ 1 …
