IndIGO, the Indian Initiative in Gravitational-wave Observations, is an initiative to set up advanced experimental facilities, with appropriate theoretical and computational support, for a multi-institutional Indian national project in gravitational-wave astronomy. Since 2009, the IndIGO Consortium has been involved in constructing the Indian road-map for Gravitational Wave Astronomy and a phased strategy towards Indian participation in realizing the crucial gravitational-wave observatory in the Asia-Pacific region. The current major IndIGO plans on gravitational-wave astronomy relate to the LIGO-India project. LIGO-India is a planned advanced gravitational-wave detector to be located in India, to be built and operated in collaboration with the LIGO USA and its international partners Australia, Germany and the UK. The project recently received the in-principle approval from the Indian government.

Theoretical physicist Bala Iyer has been recently conferred an honorary doctorate by the Central University of Karnataka "in recognition of his meritorious contributions to the field of Science.” Professor Iyer has made pioneering contributions to the calculation of expected gravitational-wave signals from inspiralling binaries of black holes and neutron stars — the kind of signals that was recently detected by LIGO and Virgo.

Applications invited for the LIGO-IndIGO Summer Students Program

Published At: 2017-12-07 03:34 -
LIGO Laboratory at California Institute of Technology hosts a 10-week summer student research program every year, called the LIGO SURF Program. In consideration of the upcoming LIGO-India project, LIGO has graciously agreed to host a few talented and motivated undergraduate students from Indian institutions, pre-selected by IndIGO, as part of this program.

Cosmic fireworks: First joint detection of gravitational and electromagnetic waves from colliding neutron stars

The beginning of gravitational-wave multimessenger astronomy
Published At: 2017-10-16 19:30 -
17 August 2017 saw a major breakthrough in astronomy, when gravitational waves from a pair of colliding neutron stars were detected for the first time by the US-based Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Europe-based Virgo. This happens to be the strongest gravitational-wave signal detected so far, owing to the relatively close location of about 130 million light-years from earth. The detection was also confirmed by a large number of telescopes around the world that studied various forms of radiation from the merger. This is a new milestone in the success saga of advanced gravitational wave detectors, which have announced the discoveries of four black hole mergers to date. The first such detection in 2015 led to the awarding of the Nobel prize in physics this year.

The existence of gravitational waves is one of the most intriguing predictions of the General Theory of Relativity proposed by Albert Einstein in 1915. Gravitational waves are distortions in the spacetime geometry that propagate with the speed of light, analogous to ripples on the surface of a pond. On 2015 September 14, the two Advanced LIGO observatories in the USA made the first direct observation of gravitational waves passing through the earth. This signal was produced by the merger of two black holes at a distance of 1.3 billion light years. This is the first of the many expected observations of this kind, that will establish the filed of gravitational-wave astronomy , opening a new window on to the Universe.
