S. Chandrasekhar was an Indian-American astrophysicist who won the Nobel Prize in Physics in 1983 for his work on the theory of black holes.

IndIGO stands for Indian Initiative in Gravitational-wave Observations and is a proposed gravitational wave observatory in India.

The primary goal of the IndIGO project is to detect gravitational waves from black hole mergers, which are among the most violent events in the universe.

The Inter-University Centre for Astronomy and Astrophysics (IUCAA) is leading the IndIGO project.

The IndIGO project is expected to be completed by 2035.

The IndIGO observatory will have three detectors.

The first IndIGO detector is named IndIGO-A.

The IndIGO-A detector will be located in Ooty, Tamil Nadu.

Each arm of the IndIGO-A detector is 4 km long.

The sensitivity of the IndIGO-A detector is 10^-24 m/√Hz.

The expected range of the IndIGO-A detector is 300 Mpc.

The expected number of black hole merger detections per year by the IndIGO-A detector is 20.

The IndIGO project will contribute to the global effort to study gravitational waves in all of the ways mentioned above.

The IndIGO project hopes to answer a wide range of scientific questions, including the nature of dark matter, the origin of the universe, and the properties of neutron stars.

The IndIGO project will benefit India's scientific community in all of the ways mentioned above.
