Tracing the redshift evolution of Hubble parameter with gravitational-wave standard sirens
Tracing the redshift evolution of Hubble parameter with gravitational-wave standard sirens
Proposed space-based gravitational-wave detectors such as BBO and DECIGO can detect ~10^6 neutron-star binaries and determine luminosity distance to the binaries with a high precision. Combining the luminosity distance and electromagnetically-derived redshift, one would be able to probe cosmological expansion out to high redshift. In this paper, we show that …
