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.
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 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.
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 ...
In June 2020, astronomers reported details of a compact binary merging, in the "mass gap" of cosmic collisions, of a first-ever 2.50–2.67 M ☉ "mystery object", either an extremely heavy neutron star (that was theorized not to exist) or a too-light black hole, with a 22.2–24.3 M ☉ black hole, that was detected as the gravitational wave GW190814.
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 ...
In gravitational-wave astronomy, observations of gravitational waves are used to infer data about the sources of gravitational waves. Sources that can be studied this way include binary star systems composed of white dwarfs , neutron stars , and black holes ; events such as supernovae ; and the formation of the early universe shortly after the ...
