Constraints on the cosmic expansion history from GWTC-3
The LIGO Scientific Collaboration, the KAGRA Collaboration, R. Abbott, H. Abe et autres
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 …
