Description
Inspiralling compact binaries are excellent standard sirens (the
gravitational wave counterpart to standard candles), in that their
gravitational wave measurements allow for self-calibrated absolute source
distances. Therefore, when coupled with independent electromagnetic redshift
measures, standard sirens allow us to map out the Universe's expansion
history and enable precision
estimates of cosmological parameters. We discuss here how well gravitational
wave measurements of inspiralling compact binaries, together with
simultaneous electromagnetic observations of short hard gamma ray bursts,
constrain cosmological
parameters (e.g., the Hubble constant) using different network
configurations of advanced ground-based gravitational wave detectors. We finally address what constraints on short hard gamma ray burst progenitor models are possible using only a
single channel of GW measurements.
