Using simulated binary black hole mergers and neutral hydrogen maps, the radio sirens method constrains H0 to 8% precision with 3000 high-SNR events, offering a 90% improvement over standard dark siren analyses.

Statistical redshifts inferred from mass spectrum features and galaxy catalogs for 142 GW events yield H0 = 76.6 km s^{-1} Mpc^{-1} and Ξ0 = 1.2, consistent with general relativity.
Analysis of 236 GW events from GWTC-5.0 constrains H0 to 71.0 +9.0/-7.1 km/s/Mpc and finds no evidence for modified gravitational-wave propagation.

GWTC-5.0: Constraints on the Cosmic Expansion Rate and Modified Gravitational-wave Propagation
Analysis of 236 GW events from GWTC-5.0 constrains H0 to 71.0 +9.0/-7.1 km/s/Mpc and finds no evidence for modified gravitational-wave propagation.
