Nobel Prize in Physics: 37 Indian Scientists Co-authored Winners’

In news

A total of 37 Indian scientists contributed and co-authored the gravitational waves discovery paper which has been awarded the 2017 Nobel Prize in Physics who are from nine institutes, including Inter-University Centre for Astronomy and Astrophysics (IUCAA).

Highlights

Sanjeev Dhurandhar, a trailblazer in gravitational waves astronomy in India,

said that Indians played a major role in the Nobel Prize-winning gravitational waves discovery paper.

He also said that the Indians contributed especially in “extracting signal from noise, in detecting the gravitational waves”.

Currently, Indian participation in the international LIGO Science Collaboration, has over 60 researchers, constituting five of the members of the LSC, making it the fourth largest national participant.
The Indian team comprising 70 scientists across 13 institutes believe the Nobel Prize couldn’t have come at a better time with India set to build the third gravitational wave detector (LIGO-INDIA) — most likely in Maharashtra.
At present, the US has two observatories while Italy houses the third called the Virgo Interferometer.

Background

Gravitational waves, first predicted by Albert Einstein more than 100 years ago, were first detected in September 2015 in the Laser Inferometer Gravitational Observatory (LIGO) 

India’s participation to LIGO and the discovery as a consequence began in the late 1980s when Indian scientists started collaborating with LIGO group in the US to detect gravitational waves.

The detection of gravitational waves has been among the major discoveries in the last 100 years. It’s a collaboration that involves expertise in diverse discipline

It is designed to open the field of gravitational-wave astrophysics through the direct detection of gravitational waves predicted by Einstein’s General Theory of Relativity.

LIGO’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves from cataclysmic cosmic sources such as the mergers of pairs of neutron stars or black holes, or by supernovae.
