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 …

We review the topic of 4D Einstein–Gauss–Bonnet (4DEGB) gravity, which has been the
subject of considerable interest over the past two years. Our review begins with a general …

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 …

On April 1st, 2019, the Advanced Laser Interferometer Gravitational-Wave Observatory
(aLIGO), joined by the Advanced Virgo detector, began the third observing run, a year-long …

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 …

Gravitational wave (GW) detection in space probes the GW spectrum that is inaccessible
from the Earth. In addition to the LISA project led by the European Space Agency, and the …

Pulsar timing data used to provide upper limits on a possible stochastic gravitational wave
background (SGWB). However, the NANOGrav Collaboration has recently reported strong …

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 …
