The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

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 …

Gravitational waves enable tests of general relativity in the highly dynamical and strong-field
regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the …

The ever-increasing number of detections of gravitational waves (GWs) from compact
binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever …

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 detection of gravitational waves by Advanced LIGO and Advanced Virgo provides an
opportunity to test general relativity in a regime that is inaccessible to traditional …

We present the results from three gravitational-wave searches for coalescing compact
binaries with component masses above 1 M⊙ during the first and second observing runs of …

Gravitational-wave observations have become an important new means to learn about the
Universe. The LIGO Scientific Collaboration and the Virgo Collaboration (LVC) have …
