264 binary black hole mergers across three LIGO/Virgo/KAGRA catalogs, plotted by luminosity distance. Each dot is a gravitational wave detection — signals that left their source between 200 Mpc and 17,000 Mpc away.
Event count by luminosity distance
Luminosity distances from IMRPhenomXPHM posterior medians (GWOSC). GWTC-2.1 = Zenodo:6513631 · GWTC-3 = Zenodo:8177023 · GWTC-4 = Zenodo:16053484. Horizontal dashed line marks predicted n = 5.314. Band shading shows ±0.15 octave window. Hover over dots for event details.
