Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

The birth of gravitational wave astronomy was triggered by the first detection of a signal
produced by the merger of two compact objects (also known as a compact binary …

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 …

Results are presented of searches for continuous gravitational waves from 20 accreting
millisecond x-ray pulsars with accurately measured spin frequencies and orbital parameters …

Transient gravitational waves (GWs) from compact binary coalescences (Abbott et al. 2019b,
2021a) have been directly observed by the Advanced Laser Interferometer Gravitational …

Continuous gravitational waves are long-lasting forms of gravitational radiation produced by
persistent quadrupolar variations of matter. Standard expected sources for ground-based …

Continuous gravitational waves are nearly monochromatic signals emitted by asymmetries
in rotating neutron stars. These signals have not yet been detected. Deep all-sky searches …

We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic
stochastic gravitational-wave background using the data from the first three observing runs …

The Virgo detector, based at the EGO (European Gravitational Observatory) and located in
Cascina (Pisa), played a significant role in the development of the gravitational-wave …

Seven years after the first direct detection of gravitational waves, from the collision of two
black holes, the field of gravitational wave astronomy is firmly established. A first detection of …
