Hierarchical analysis of GWTC-3 events measures effective compactness C_eff = 0.5^{+0.3}_{-0.1} consistent with black holes and limits low-compactness exotic merger rate to <0.7 Gpc^{-3} yr^{-1}.
The chirp-mass distribution of GW-detected binary black holes shows a ladder of peaks doubling in mass, with a new intermediate peak at 19 solar masses confirming a prior prediction from the hierarchical merger model.
