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 …

Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

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 …

Abstract The Einstein Telescope (ET), a proposed European ground-based gravitational-
wave detector of third-generation, is an evolution of second-generation detectors such as …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

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 …

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 …
