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 gravitational-wave discoveries from compact binary coalescences detected by
Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between …

We report the observation of gravitational waves from a binary-black-hole coalescence
during the first two weeks of LIGO's and Virgo's third observing run. The signal was recorded …

The growing population of compact binary mergers detected with gravitational waves
contains multiple events that are challenging to explain through isolated binary evolution …

Gravitational waves emitted by neutron star black hole mergers encode key properties of
neutron stars—such as their size, maximum mass, and spins—and black holes. However, it …

Third-generation (3G) gravitational wave detectors, in particular Einstein Telescope (ET) and
Cosmic Explorer (CE), will explore unprecedented cosmic volumes in search for compact …

We present a reduced-order surrogate model of gravitational waveforms from nonspinning
binary black hole systems with comparable to large mass-ratio configurations. This …

This article introduces varaha, an open-source, fast, non-Markovian sampler for estimating
gravitational-wave posteriors. varaha differs from existing nested sampling algorithms by …

Numerical relativity simulations provide the most precise templates for the gravitational
waves produced by binary black hole mergers. However, many of these simulations use an …

Faster likelihood evaluation enhances the efficiency of gravitational wave signal analysis.
We present mode-by-mode relative binning, a new method designed for obtaining fast and …
