We report the detection of ten new binary black hole (BBH) mergers in the publicly released
data from the first half of the third observing run (O3a) of advanced LIGO and advanced
Virgo. We identify candidates using an updated version of the search pipeline described in

We report the detection of 5 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
LIGO and advanced Virgo. The LIGO-Virgo-KAGRA (LVK) collaboration reported 35
compact binary coalescences (CBCs) in their analysis of the O3b data [1], with 30 BBH
mergers having coincidence in the Hanford and Livingston detectors. We confirm 17 of these
for a total of 22 detections in our analysis of the Hanford-Livingston coincident O3b data. We …
