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 …

Since the early stages of operation of ground-based gravitational-wave interferometers,
careful monitoring of these detectors has been an important component of their successful …

Measurement of spin-precession in black hole binary mergers observed with gravitational
waves is an exciting milestone as it relates to both general relativistic dynamics and …

The current generation of very-high-energy gamma-ray (VHE; E> 30 GeV) detectors (MAGIC
and HESS) have recently demonstrated the ability to detect the afterglow emission of …

Along their path from source to observer, gravitational waves may be gravitationally lensed
by massive objects leading to distortion in the signals. Searches for these distortions …

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

Starting from May 2023, the LIGO Scientific, Virgo and KAGRA Collaboration has been
conducting the fourth observing run with improved detector sensitivities and an expanded …

Precession in binary black holes (BBH) is caused by the failure of the black hole spins to be
aligned and its study can open up new perspectives in gravitational wave astronomy …

Premerger localization of binary neutron stars (BNSs) is one of the most important scientific
goals for the third-generation (3G) gravitational-wave detectors. It will enable the …

We propose a novel signal-consistency test applicable to a broad search for gravitational
waves emitted by generic binary black hole (BBH) systems. The test generalizes the time …
