Prospects for Measuring the Hubble Constant with Neutron-Star–Black-Hole Mergers
Prospects for Measuring the Hubble Constant with Neutron-Star–Black-Hole Mergers
Gravitational wave (GW) and electromagnetic (EM) observations of neutron-star-black-hole (NSBH) mergers can provide precise local measurements of the Hubble constant ($H_0$), ideal for resolving the current $H_0$ tension. We perform end-to-end analyses of realistic populations of simulated NSBHs, incorporating both GW and EM selection for the first time. We show …
