GWTC BBH mergers have typical recoil kicks of ~300–330 km/s, with retention of only ~2–3% in globular clusters; hierarchical-merger prospects depend on both retention and post-kick re-centering.

Next-generation GW detector networks can constrain the spatial curvature parameter Ω_k to 1σ uncertainty of 0.029 using intermediate-mass binary black hole bright sirens.
Two asymmetric BBH mergers are characterized with mass ratios 0.35 and ≤0.20; one shows high spins, negative χ_eff, and strong precession, suggesting an emerging population of massive rapidly spinning systems.
GWTC-2.1 adds eight new high-significance compact binary coalescence events to the prior catalog, extending the observed black hole mass range and including candidates inside the pair-instability mass gap.

Recoil kicks from binary black hole mergers in GWTC catalogs: implications for retention and hierarchical mergers
GWTC BBH mergers have typical recoil kicks of ~300–330 km/s, with retention of only ~2–3% in globular clusters; hierarchical-merger prospects depend on both retention and post-kick re-centering.

GWTC-2.1: Deep Extended Catalog of Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run
GWTC-2.1 adds eight new high-significance compact binary coalescence events to the prior catalog, extending the observed black hole mass range and including candidates inside the pair-instability mass gap.
