New black hole mergers from a search pipeline for gravitational waves with higher-order harmonics

Nearly all of the previous gravitational wave (GW) searches in the LIGO-Virgo data included GW waveforms with only the dominant quadrupole mode, i.e., omitting higher-order harmonics which are predicted by general relativity. I will present detections of ~10 new black hole mergers in the LIGO-Virgo O3 data from a novel search pipeline that includes the higher-order harmonics. Some of the new detections have astrophysically interesting properties such as BH masses in the IMBH and upper mass gap ranges, high-redshifts (1<z<2), asymmetric mass ratios and positive effective spins.
