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.
Forecasts that golden and silver dark sirens with HETDEX VIRUS follow-up can constrain H0 to a few percent using one year of LIGO-A# observations for z < 0.2 events.
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.
