New black hole mergers in the LIGO-Virgo O3 data from a gravitational wave search including higher-order harmonics
Digvijay Wadekar, Javier Roulet, Tejaswi Venumadhav +5
Nearly all of the previous gravitational wave (GW) searches in the LIGO-Virgo data included GW waveforms with only the dominant quadrupole harmonic, i.e., omitting higher-order har…

New binary black hole mergers in the LIGO-Virgo O3b data
Ajit Kumar Mehta, Seth Olsen, Digvijay Wadekar +5
We report the detection of 6 new candidate binary black hole (BBH) merger signals in the publicly released data from the second half of the third observing run (O3b) of advanced LI…

New approach to template banks of gravitational waves with higher harmonics: Reducing matched-filtering cost by over an order of magnitude
Digvijay Wadekar, Tejaswi Venumadhav, Ajit Kumar Mehta +5
Searches for gravitational wave events use models, or templates, for the signals of interest. The templates used in current searches in the LIGO-Virgo-Kagra (LVK) data model the do…
