Educational observatory This is a partial list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation.
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.
Gravitational waves were first predicted in 1916 by Einstein, who was trying to understand how gravity moves in the cosmos. Learn about gravitational waves and how a Tri-Cities observatory spots ...
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]).
Known gravitational wave events come from the merger of two black holes (BH), two neutron stars (NS), or a black hole and a neutron star (BHNS). [ 9 ] [ 10 ] Some objects are in the mass gap between the largest predicted neutron star masses ( Tolman–Oppenheimer–Volkoff limit ) and the smallest known black holes.
In 2015 the Laser Interferometer Gravitational-wave Observatory at Hanford site land in Eastern Washington and its twin observatory in Louisiana detected gravitational waves for the first time ...
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
