A dark standard siren measurement of the Hubble constant following LIGO/Virgo/KAGRA O4a and previous runs
C. R. Bom, V. Alfradique, A. Palmese +4
We present a new constraint on the Hubble constant () from the standard dark siren method using a sample of well-covered gravitational waves (GW) alerts reported during th…
