Adhikari has been involved in the construction and design of gravitational-wave detectors since 1997. [19] He started working on laser interferometers as a graduate student at MIT, with a particular focus on the variety of noise sources, feedback loops and subsystems, [20] [21] and helped to reduce the noise in all 3 of the LIGO interferometers while working on the Livingston interferometer.
The Sanford Underground Research Facility (SURF), or Sanford Lab, is an underground laboratory in Lead, South Dakota. The deepest underground laboratory in the United States, it houses multiple experiments in areas such as dark matter and neutrino physics research, biology, geology and engineering. There are currently 28 active research ...
The LIGO Laboratory, in collaboration with the US National Science Foundation and Advanced LIGO partners from the U.K., Germany and Australia, has offered to provide all of the designs and hardware for one of the three planned Advanced LIGO detectors to be installed, commissioned, and operated by an Indian team of scientists in a facility to be ...
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 ...
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.
Executive director, LIGO Laboratory; research professor of physics, California Institute of Technology; professor of physics, University of Florida David Howard Reitze (born 6 January 1961) is an American laser physicist who is professor of physics at the University of Florida and served as the scientific spokesman of the Laser Interferometer ...
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 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.
