The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

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 …

The second Gravitational-Wave Transient Catalog, GWTC-2, reported on 39 compact binary
coalescences observed by the Advanced LIGO and Advanced Virgo detectors between 1 …

We report the detection of ten new binary black hole (BBH) mergers in the publicly released
data from the first half of the third observing run (O3a) of advanced LIGO and advanced …

The Advanced LIGO [1] and Advanced Virgo [2] detectors have made numerous detections
of gravitational waves (GWs), to date consisting of short-duration (transient) GWs emitted …

With several dozen binary black hole events detected by LIGO-Virgo to date and many more
expected in the next few years, gravitational-wave astronomy is shifting from individual …

We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular
clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamically …

Gravitational-wave detectors are starting to reveal the redshift evolution of the binary black
hole (BBH) merger rate, R BBH (z). We make predictions for R BBH (z) as a function of black …
