Abstract

Recently the LIGO and Virgo Collaborations reported on 39 candidate gravitational wave discoveries from compact binary coalescences detected by Advanced LIGO and Advanced Virgo between 1 April 2019 and 1 October 2019. This new catalog contains events whose sources are black hole binary mergers up to a redshift of $\sim$0.8, as well as events which could plausibly originate from binary neutron stars, neutron star-black hole binaries, or binary black holes. The candidate events which are unambiguously identified as binary black holes (both objects }$\ge 3 \mathrm{M}_\odot$ have total masses between $\sim 14 \mathrm{M}_\odot$ and $\sim 150 \mathrm{M}_\odot$. I will describe these new discoveries and provide an overview of ongoing activities in the LIGO/Virgo search for compact binary coalescences.
