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 report results of a search for an isotropic gravitational-wave background (GWB) using
data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with …

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 report results from searches for anisotropic stochastic gravitational-wave backgrounds
using data from the first three observing runs of the Advanced LIGO and Advanced Virgo …

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 …

We develop a detailed anisotropic model for the astrophysical gravitational-wave
background, including binary mergers of two stellar-mass black holes, two neutron stars, or …

Genetic studies have shown essential functions of O-linked N-acetylglucosamine (O-
GlcNAc) modification in plants. However, the proteins and sites subject to this …

We employ gravitational-wave radiometry to map the stochastic gravitational wave
background expected from a variety of contributing mechanisms and test the assumption of …
