I have seen this and am already wondering if I can present the GWTC-4 marginal posteriors this way.
So, what can we say about the latest GWTC 4 catalogue?
In some ways, it's not too surprising, it's a 'firming up' of the clues we were getting from GWTC 3. But there's a couple of neat things: So, AGN channel perspective follows

Evidence For Three Binary Black Hole Subpopulations At Different Primary Masses Supports GWTC-4 Data
Analysis of gravitational wave data reveals that merging black holes fall into at least three distinct groups, each defined by differing masses and spin rates, suggesting multiple pathways for their formation in the universe.

The bias in chi_eff among the higher spin BH tests this fraction of prograde:retrograde mergers in AGN. Note also the preferred plane of the AGN weakens the strong limits on hierarchical mergers from GWTC 4, since those assume isotropic spins.
