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 proposed advanced gravitational-wave detector to be located in India, whose concept proposal is now under active consideration by the science funding agencies in India and USA.


The Advanced LIGO gravitational-wave observatories in the USA have been officially dedicated in a ceremony held on Tuesday, May 19, at the LIGO Hanford facility in Richland, Washington state. This marks a major step in the international effort for the first direct detection of gravitational waves.

The International Centre for Theoretical Sciences, TIFR is organizing a Summer School on Gravitational Wave Astronomy in Bangalore from The school is aimed at training students and young researchers in the emerging area of gravitational-wave astronomy.
LIGO Laboratory at California Institute of Technology hosts a 10-week summer student research program every year, called the LIGO SURF Program. Considering the imminent possibility of the 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.

The existence of gravitational waves(external link) is one of the most intriguing predictions of the General Theory of Relativity(external link) proposed by Albert Einstein(external link) 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. Although indirect evidence for the existence of gravitational waves is obtained from the observation of binary pulsars(external link), a direct detection of gravitational waves is yet to be done. A world-wide network of gravitational-wave detectors has started an exciting search for these ripples in spacetime. These observatories will establish the filed of gravitational-wave astronomy(external link), opening a new window on to the Universe.
