Newly detected merging Black Holes establish Gravitational Waves as a powerful tool to explore the unseen Universe Indian researchers contribute to breakthroughs in various frontiers of Cosmology and Astrophysics using a newly compiled Gravitational Wave Transient Catalog

The LIGO-Virgo-KAGRA (LVK) Collaboration recently released the largest catalog ever of Gravitational-wave (GW) detections and a number of scientific analyses that use this catalog. These gravitational waves, or ripples in spacetime were emitted during collisions of massive cosmic objects (like black holes and neutron stars). Data from three detectors have been carefully analysed by scientists from an international GW observatory network: two detectors of the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) in Louisiana and Washington state in the US and the Advanced Virgo detector in Italy.
