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 …

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 …

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 …

A wide variety of astrophysical and cosmological sources are expected to contribute to a
stochastic gravitational-wave background. Following the observations of GW150914 and …

We present new limits on an isotropic stochastic gravitational-wave background (GWB)
using a six pulsar data set spanning 18 yr of observations from the 2015 European Pulsar …

The production of a stochastic background of gravitational waves is a fundamental
prediction of any cosmological inflationary model. The features of such a signal encode …

Between July 2009 and October 2010, the Laser Interferometer Gravitational-Wave
Observatory (LIGO)[1] operated two 4 km laser interferometers as part of a global network …

In this work, we study the prospect of detecting the stochastic gravitational-wave background
with the TianQin Observatory. We consider sources of both astrophysical and cosmological …

The Laser Interferometer Gravitational Wave Observatory (LIGO) consists of two widely
separated 4 km laser interferometers designed to detect gravitational waves from distant …

Quantum fluctuations of the gravitational field in the early Universe, amplified by inflation,
produce a primordial gravitational-wave background across a broad frequency band. We …
