Welcome

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.

NEWS LIGO Detects Gravitational Waves for the Third Time Firmly transiting into the era of Gravitational Wave Astronomy Published At: 2017-06-01 20:30 - The Laser Interferometer Gravitational-wave Observatory (LIGO) has made another successful detection of gravitational waves, ripples in space and time, from the merger of two massive black holes that happened three billion light years away. This firmly reiterates the remarkable launch, announced last year, of a new window of astronomy.

Vishveshwara, who passed away in Bangalore recently, was one of the true pioneers of black hole physics. His notable contributions include the proof of the stability of Schwarzschild black holes and the discovery of quasi-normal modes of black holes. Read More Applications invited for the LIGO-IndIGO Summer Students Program Published At: 2016-12-29 23:53 - LIGO Laboratory at California Institute of Technology hosts a 10-week summer student research program every year, called the LIGO SURF Program. In consideration to 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.

GRAVITATIONAL WAVES 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.
