Neutron star – Black hole Merger Discovery: First Hybrid Stellar Collision

#GWGreatestHits Until recently, the global array of GW detectors had been able to detect collisions between pairs of either black holes or neutron stars. For the first time in January 2020, the LIGO-Virgo network of detectors made the ground-breaking discovery of gravitational waves from two events, each a “hybrid” merger, collision between a neutron star and a black hole.

Indian researchers from the LIGO-India Scientific Collaboration (LISC) contributed to this major discovery. In particular, Dr. Shasvath Kapadia from the International Centre for Theoretical Sciences (ICTS) in Bengaluru helped with the estimation of the NS-BH merger rate, using a method he co-developed.
