Inferring the cosmological constant in early Universe only by gravitational waves

Abstract Gravitational waves (GWs) from compact binary coalescence (CBC) can directly determine the luminosity distance but usually can not obtain information about the redshift. This assumes that the GW source is at the flat background. However, if the GWs are generated in a not flat but accelerati...
