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.

Methodological choices in dark siren cross-correlations can mitigate biases in H0 inference when selection effects are built into the model and samples of precise events are sufficiently large.
A robust statistical test for galaxy catalog magnitude completeness improves H0 constraints by 1.3-8.6% in GWTC-1 analyses but shows no benefit for GWTC-3 due to limited K-band coverage in GLADE+.
