O3 – IMBH – Search for Intermediate Mass Black holes

#GWGreatestHits Intermediate Mass Black holes (IMBH) are missing links between stellar-mass and supermassive black holes, and have been the focus of attention for astronomers for many years. A combined search by Advanced LIGO/Virgo & KAGRA in their third observing run O3 led to a better understanding of these mysterious objects.

The search for IMBHs by LIGO-Virgo-KAGRA Collaboration had important contributions from Indian Scientists from the LIGO-India Scientific Collaboration (LISC). Prof. Archana Pai and her students Koustav Chandra, Nirban Bose from IIT Bombay, and Kanchan Soni from IUCAA were involved in the matched filter bank development as well as in carrying out this search along with their collaboration colleagues.
