Gravitational wave observations, distance measurement uncertainties, and cosmology
Gravitational waves from the coalescence of compact binaries, together with an associated electromagnetic counterpart, are ideal probes of cosmological models. As demonstrated with GW170817, such multimessenger observations allow one to use the source as a standard siren, the analog of standard candles in conventional astronomy, in order to measure cosmological …
