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 …

A stochastic background of gravitational waves could be created by the superposition of a
large number of independent sources. The physical processes occurring at the earliest …

We review detection methods that are currently in use or have been proposed to search for a
stochastic background of gravitational radiation. We consider both Bayesian and frequentist …

Recent table-top optical interferometry experiments, and advances in gravitational-wave
detectors have demonstrated the capability of optical interferometry to detect displacements …

A stochastic background of gravitational waves with astrophysical origins may have resulted
from the superposition of a large number of unresolved sources since the beginning of …

Significant progress has been made in recent years on the development of gravitational-
wave detectors. Sources such as coalescing compact binary systems, neutron stars in low …

Gravitational wave science should transform in this decade from a study of what has not
been seen to a full-fledged field of astronomy in which detected signals reveal the nature of …

Future missions of gravitational-wave astronomy will be operated by space-based
interferometers, covering a very wide range of frequencies. Search for stochastic …

Primordial gravitational waves (GWs) with frequencies≳ 10− 15 Hz contribute to the
radiation density of the Universe at the time of decoupling of the cosmic microwave …

Double black hole binaries are among the most important sources of gravitational radiation
for ground-based detectors such as LIGO or VIRGO. Even if formed with lower efficiency …
