N2 - We use 47 gravitational-wave sources from the Third LIGO-Virgo-KAGRA Gravitational-Wave Transient Catalog (GWTC-3) to estimate the Hubble parameter \(H(z)\), including its current value, the Hubble constant \(H_0\). Each gravitational-wave (GW) signal provides the luminosity distance to the source and we estimate the corresponding redshift using two methods: the redshifted masses and a galaxy catalog. Using the binary black hole (BBH) redshifted masses, we simultaneously infer the source mass distribution and \(H(z)\). The source mass distribution displays a peak around \(34\, {\rm M_\odot}\), followed by a drop-off. Assuming this mass scale does not evolve with redshift results in a \(H(z)\) measurement, yielding \(H_0=68^{+12}_{-7} {\rm km\,s^{-1}\,Mpc^{-1}}\) (\(68\%\) credible interval) when combined with the \(H_0\) measurement from GW170817 and its electromagnetic counterpart. This represents an improvement of 17% with respect to the \(H_0\) estimate from GWTC-1. The second method associates each GW event with its probable host galaxy in the catalog GLADE+, statistically marginalizing over the redshifts of each event's potential hosts. Assuming a fixed BBH population, we estimate a value of \(H_0=68^{+8}_{-6} {\rm km\,s^{-1}\,Mpc^{-1}}\) with the galaxy catalog method, an improvement of 42% with respect to our GWTC-1 result and 20% with respect to recent \(H_0\) studies using GWTC-2 events. However, we show that this result is strongly impacted by assumptions about the BBH source mass distribution; the only event which is not strongly impacted by such assumptions (and is thus informative about \(H_0\)) is the well-localized event GW190814.
