C. V. Vishveshwara is widely regarded as the father of Indian gravitational wave research. He was a renowned physicist who made significant contributions to the field of gravitational waves and black hole physics.

Tata Institute of Fundamental Research, Mumbai is a major contributor to the Laser Interferometer Gravitational-Wave Observatory (LIGO) project. It is one of the few institutions outside the United States that is involved in this project.

LIGO-India is the name of the Indian gravitational wave detector that is currently under construction. It is a joint project between India and the United States, and it is expected to be completed by 2035.

Black holes are the primary sources of gravitational waves. When two black holes merge, they produce powerful gravitational waves that can be detected by gravitational wave detectors.

GW150914 is the name of the first black hole binary system that was detected by gravitational waves. It was detected by the LIGO detectors in September 2015.

The mass range of black holes that are typically involved in gravitational wave mergers is 10-1000 solar masses. This is the mass range of black holes that are formed by the collapse of massive stars.

S. Chandrasekhar is the Indian scientist who played a key role in the development of the theory of gravitational waves. He was a renowned physicist who won the Nobel Prize in Physics in 1983 for his work on the theory of white dwarf stars.

IndIGO is the name of the Indian gravitational wave observatory that is planned to be built in the Himalayas. It is a proposed project that is still in the early stages of development.
