While most of the compact-binary mergers detected by LIGO and Virgo are expected to
consist of first-generation black holes formed from the collapse of stars, others might instead …

The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with
Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the …

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 …

Hierarchical analysis of binary black hole (BBH) detections by the Advanced LIGO and Virgo
detectors has offered an increasingly clear picture of their mass, spin, and redshift …

The LIGO and Virgo gravitational-wave detectors have uncovered binary black hole systems
with definitively nonzero spins, as well as systems with significant spin residing in the more …

The population-level distributions of the masses, spins, and redshifts of binary black holes
(BBHs) observed using gravitational waves can shed light on how these systems form and …

We present IMRPhenomXODE, a new phenomenological frequency-domain waveform
approximant for gravitational wave (GW) signals from precessing binary black holes (BBHs) …

The spins of merging binary black holes offer insights into their formation history. Recently it
has been argued that in the isolated binary evolution of two massive stars the firstborn black …

Binary black holes formed via different pathways are predicted to have distinct spin
properties. Measuring these properties with gravitational waves provides an opportunity to …

Population inference of gravitational-wave catalogues is a useful tool to translate
observations of black hole mergers into constraints on compact-binary formation. Different …
