The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. [1]
It was published in 2020 that a gamma-ray burst was detected ~0.5 seconds after the LIGO trigger, lasting 6 seconds and bearing similarities to GRB170817 (such as weakness [most power in sub-100 keV, or soft X-rays) bands], elevated energetic photon background levels [signal exceeding background by less than a factor of 2], and similar ...
The LSC was established in 1997, under the leadership of Barry Barish. [3] Its mission is to ensure equal scientific opportunity for individual participants and institutions by organizing research, publications, and all other scientific activities, and it includes scientists from both LIGO Laboratory and collaborating institutions.
The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. [3] [4] [5] Previously, gravitational waves had been inferred only indirectly, via their effect on the timing of pulsars in binary star systems.
The IndIGO Consortium has spearheaded the proposal for the LIGO-India gravitational wave observatory, in association with the LIGO laboratory in US.In addition to the LIGO-India project, the other activities of IndIGO involve facilitating international collaborations in gravitational-wave physics and astronomy, initiating a strong experimental gravitational-wave research program in India ...
LIGO is a 2019 American documentary film that tells the inside account of the discovery by the international LIGO Scientific Collaboration of the first observation of gravitational waves in September 2015, [1] a discovery that led two years later to the Nobel Prize in Physics for LIGO physicists Rai Weiss, Kip Thorne and Barry Barish. [2]
An automatic computer search of the LIGO-Hanford datastream triggered an alert to the LIGO team about 6 minutes after the event. The gamma-ray alert had already been issued at this point (16 seconds post-event), [21] so the timing near-coincidence was automatically flagged. The LIGO/Virgo team issued a preliminary alert (with only the crude ...
Ronald William Prest Drever (26 October 1931 – 7 March 2017) was a Scottish experimental physicist. He was a professor emeritus at the California Institute of Technology, co-founded the LIGO project, and was a co-inventor of the Pound–Drever–Hall technique for laser stabilisation, as well as the Hughes–Drever experiment.
