GW190412: The merger of two black holes with unequal masses
April 12, 2020
The LIGO and Virgo Collaborations have observed gravitational waves produced by the inspiral and merger of two black holes. The signal, named GW190412, was produced by a coalescing BBH system with unequal masses, one component being more than 3 times heavier than the other one.
Virgo and LIGO join forces for a new year-long signal hunt
March 26, 2019
The Virgo and LIGO detectors are ready to start the new Observing run called O3, lasting a whole year. The hunt for gravitational waves is set to start on April 1st when the Virgo detector and the LIGO twin detectors will start to take data becoming together the most sensitive gravitational wave observatory to date
LIGO and Virgo Announce Four New Gravitational-Wave Detections
December 3, 2018
The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical remains of stellar explosions. Six of the black hole merger events had been reported before, while four are newly announced.
