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 …

Although the dark matter is usually assumed to be made up of some form of elementary
particle, primordial black holes (PBHs) could also provide some of it. However, various …

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 …

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 …

On May 21, 2019 at 03: 02: 29 UTC Advanced LIGO and Advanced Virgo observed a short
duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise …

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 100 years since the publication of Albert Einstein's theory of general relativity saw
significant development of the understanding of the theory, the identification of potential …

The discovery of a gravitational wave (GW) signal from a binary neutron star (BNS) merger
(Abbott et al. 2017a) and the kilonova emission from its remnant (Coulter et al. 2017; Abbott …
