Gravitational wave detectors are already operating at interesting sensitivity levels, and they
have an upgrade path that should result in secure detections by 2014. We review the …

Gravitational-wave experiments with interferometers and with resonant masses can search
for stochastic backgrounds of gravitational waves of cosmological origin. We review both …

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 …

The stochastic gravitational-wave background is a superposition of sources that are either
too weak or too numerous to detect individually. In this study, we present the results from a …

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 …

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 …

Stochastic gravitational-wave backgrounds (SGWBs) derive from the superposition of
numerous individually unresolved gravitational-wave (GW) signals. Detecting SGWBs …

The anisotropies of the Cosmological Gravitational Wave Background (CGWB) retain
information about the primordial mechanisms that source the gravitational waves and about …

Beyond individually resolvable gravitational wave events such as binary black hole and
binary neutron star mergers, the superposition of many more weak signals coming from a …

Gravitational-wave emission from stellar collapse has been studied for nearly four decades.
Current state-of-the-art numerical investigations of collapse include those that use …
