Determining the Cosmic Equation of State Using Future Gravitational Wave Detectors
Abstract
The expected chirp mass distribution of observed events for future gravitational wave detectors is extensively investigated in the presence of an exotic fluid component with an arbitrary equation of state, -1 ≤ ωx px/x < 0, i.e., the so-called dark energy component. The results for a flat model dominated by a dark energy are compared to those for the standard flat model dominated by cold dark matter. It is found that for a flat universe the chirp mass distribution shows a sensitive dependence on ωx, which may provide an independent and robust constraint on the cosmic equation of state.
