A Standard Siren Measurement of the Hubble Constant Using Gravitational-wave Events from the First Three LIGO/Virgo Observing Runs and the DESI Legacy Survey
Published 2023-01-01“…This result shows that a combination of eight well-localized dark sirens combined with an appropriate galaxy catalog is able to provide an H _0 constraint that is competitive (∼20% versus 18% precision) with a single bright standard siren analysis (i.e., assuming the electromagnetic counterpart) using GW170817. When combining the posterior with that from GW170817, we obtain ${H}_{0}={72.77}_{-7.55}^{+11.0}\,\mathrm{km}\,{{\rm{s}}}^{-1}\,{\mathrm{Mpc}}^{-1}$ . …”
