A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

Gravitational waves from binary black hole and neutron star mergers are being regularly
detected. As of 2021, 90 confident gravitational wave detections have been made by the …

We review recent progress and future prospects for harnessing powerful tools from
theoretical high-energy physics, such as scattering amplitudes and effective field theory, to …

This handbook provides an updated comprehensive description of gravitational wave
astronomy. In the first part, it reviews gravitational wave experiments, from ground and space …

The collection of individually resolvable gravitational wave (GW) events makes up a tiny
fraction of all GW signals that reach our detectors, while most lie below the confusion limit …

Upcoming observational runs of the LIGO-Virgo-KAGRA Collaboration and future
gravitational-wave (GW) detectors on the ground and in space require waveform models …

We survey the prospective sensitivities of terrestrial and space-borne atom interferometers to
gravitational waves generated by cosmological and astrophysical sources, and to ultralight …

Data from ground-based gravitational-wave detectors contains numerous short-duration
instrumental artifacts, called'glitches'. The high rate of these artifacts in turn results in a …

Boson stars have attracted much attention in recent decades as simple, self-consistent
models of compact objects and also as self-gravitating structures formed in some dark …

A major challenge for gravitational-wave (GW) detection in the μ Hz band is engineering a
test mass (TM) with sufficiently low acceleration noise. We propose a GW detection concept …
