The European Gravitational Observatory (EGO) is a consortium established to manage the Virgo interferometer and its related infrastructure, as well as to promote cooperation in the field of gravitational wave research in Europe.
The International Pulsar Timing Array (IPTA) is a multi-institutional, multi-telescope collaboration [1] comprising the European Pulsar Timing Array (EPTA), the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), the Parkes Pulsar Timing Array (PPTA) in Australia, and the Indian Pulsar Timing Array Project (InPTA [2] [3]).
The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves.The detector is a Michelson interferometer, which can detect the minuscule length variations in its two 3-km (1.9 mi) arms induced by the passage of gravitational waves.
Einstein Telescope, a European third-generation gravitational wave detector; Einstein@Home, a volunteer distributed computing program one can download in order to help the LIGO/GEO teams analyze their data; GEO600, a gravitational wave detector located in Hannover, Germany; Holometer; North American Nanohertz Observatory for Gravitational Waves
Gravitational waves (GW) are small disturbances in space-time, caused by the motion of masses, if the third time derivative of the mass quadrupole moment is non-zero. These waves are very weak, such that only the strongest waves, caused by the rapid motion of dense stars or black-holes, have a chance of being detected.
The proposal to use pulsars as gravitational wave (GW) detectors was originally made by Mikhail Sazhin [4] and Steven Detweiler [5] in the late 1970s. The idea is to treat the solar system barycenter and a galactic pulsar as opposite ends of an imaginary arm in space. The pulsar acts as the reference clock at one end of the arm sending out ...
Surface gravity mapping is often used to map out gravity anomalies such as a Bouguer anomaly or isostatic gravity anomalies. [1] Derivative gravity maps are an extension of standard gravity maps, involving mathematical analysis of the local gravitational field strength, to present data in analogous formats to a geologic map.

The Gravitational-wave Optical Transient Observer (GOTO) is an array of robotic optical telescopes optimized for the discovery of optical counterparts to gravitational wave events [1] and other multi-messenger signals. The array consists of a network of telescope systems, with each system consisting of eight 0.4m telescopes on a single mounting ...
