Gravitational Wave Transient Catalog Detection from 2015 - 2020 of compact binaries

#GWGreatestHits The largest Gravitational Wave Transient Catalog for detections between 2015-2020 was released during the third observing run O3. Most of the events were mergers of black holes, while two were neutron-star black hole mergers. Analysis of these mergers revealed a wealth of information, such as an improved estimate of the expansion rate of the Universe.

An international team of researchers, including Indian researchers from the LIGO-India Scientific Collaboration (LISC), such as Dr Surhud More from the Inter-University Centre for Astronomy & Astrophysics (IUCAA), Pune, played a key role in the determination of the Hubble constant using GW data and associated galaxy catalogs.
