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 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.
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]).
LIGO now works with other gravitational-wave observatories around the world including Virgo, in Italy, and KAGRA, in Japan. LIGO India is expected to come online in the early 2030s.
Scientists on Wednesday unveiled evidence that gravitational waves, the ripples in the fabric of space-time predicted by Albert Einstein more than a century ago, are permeating the universe at low ...
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 two laser instruments, which work in unison, are known as the Laser Interferometer Gravitational-Wave Observatory (LIGO). They are able to detect remarkably small vibrations from passing ...
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
