Recently, a good news regarding space exploration graced India. The news was that a new set of LIGO detectors will be built in India by 2025. The upcoming, new and powerful LIGO detector, to be built in India, will be of utmost importance both for Indian researchers as well as the science fraternity around the world.
Currently, there are two LIGO detectors located in the US. One is at Livingstone, and another is at Hanford. The LIGO detector, which will be built in India, will be the third set of the LIGO detectors and it will definitely boost up the gravitational waves detection capabilities of LIGO. Recently David Reitze, executive director of Laser Interferometer Gravitational-Wave Observatory (LIGO) said that the role of India in the study of gravitational waves- depicted as one of the most important and defining discoveries of the recent past- will elevate once the proposed gravitational wave observatory (LIGO) is set up in the country. He further said that the more detectors they have and depending on their locations, the more accurately and precisely their team can be able to point into the direction of the sky.
According to him, when India gets the LIGO detector, it will dramatically improve the detection capability of the LIGO Observatory. He touted the building of LIGO detectors in India as a very big mission. Some days ago, Somak Raychaudhury, Director of the Inter-University Center for Astronomy and Astrophysics (IUCAA) had informed that the specific area for the establishment of new detectors has already been chosen and after the detector building gets completed, they would be run by IUCAA. Raychaudhury also said that the LIGO-India partnership is funded by the Science and Technology Facilities Council (STFC) as a part of its Newton-Bhabha project on LIGO. In September 2015, The LIGO detectors created history when they successfully detected the first ever gravitational waves coming out from merger of two massive black holes. Gravitational waves are the ripples in fabrics of space and time.
The LIGO team is hoping that when the third LIGO detector becomes operational in India, they will be able to detect even the smallest of ripples or the so-called low-frequency gravitational waves more accurately. Mr. Reitze further also said that apart from two black hole merger and two neutron star merger, there is a chance that one neutron star and one black hole might get merged. So, their team wants to detect that merger, and also he insisted that the LIGO detectors need to be more sensitive so as to detect the gravitational waves coming out from supernovas.
