Low-redshift constraints on the Hubble constant from the baryon acoustic oscillation “standard rulers” and the gravitational wave “standard sirens”

Low-redshift constraints on the Hubble constant from the baryon acoustic oscillation “standard rulers” and the gravitational wave “standard sirens”

Abstract The multi-messenger observations of GW170817 indicated a new independent measurement of the Hubble constant ($$H_0$$ H0 ). We obtain the low-redshift cosmological constraints on $$H_0$$ H0 by combining this gravitational wave measurement with the observations of distance scales in baryon ac...
