Constraints on high-mass black hole populations from a search incorporating higher harmonics

Recent advancements in the IAS pipeline, including incorporation of higher gravitational-wave harmonics and enhanced glitch-reduction techniques, have significantly improved its sensitivity to high-mass binary black hole mergers. These upgrades have already led to the discovery of several new high-mass binary black hole mergers. In this talk, I will discuss the resulting constraints on the high-mass black hole population from our new BBH merger catalog. I will also quantify the relative improvement in sensitive volume in different regions of binary parameter space upon including higher harmonics in our search.
