Measuring the Hubble constant with a sample of kilonovae

Measuring the Hubble constant with a sample of kilonovae

Kilonovae observations can be used to out constraints on the Hubble constant (H0). Here, the authors show H0 measurements by combining light curves of four short gamma-ray burts with GW170817 are about a factor of 2-3 more precise than the standard-siren measurements using only gravitational-waves.
