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 national project in gravitational-wave astronomy. The IndIGO collaboration is in the process of constructing a road-map and a phased strategy towards building a gravitational-wave observatory in the Asia-Pacific region.
The IndIGO consortium has been accepted as a member research group of the LIGO Scientific Collaboration (LSC). LSC is an international collaboration of scientists working on gravitational-wave-observation program, and is responsible for analyzing the data collected by the LIGO observatories in the USA and the GEO 600 observatory in Germany.
The IndIGO consortium is organizing a mock gravitational-wave (GW) data challenge for students. Simulated data of a future GW observatory called "Indigo" will be provided containing simulated GW signals from inspiralling binary black holes. Participants will be asked to detect these signals using the detection algorithms that they have developed, and to report the recovered parameters of the black-hole binaries.
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. Although indirect evidence for the existence of gravitational waves is obtained from the observation of the binary pulsar PSR B1913+16, 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, opening a new window on to the Universe.

(GWIC). This marks an important recognition to the consortium by the international gravitational-wave (GW) community. GWIC was formed in 1997 to facilitate international collaboration and cooperation in the construction, operation and use of the major GW detection facilities worldwide. GWIC is affiliated with the
