The cosmological constant and advanced gravitational wave detectors
نویسندگان
چکیده
Interferometric gravitational wave detectors could measure the frequency sweep of a binary inspiral [characterized by its chirp mass] to high accuracy. The observed chirp mass is the intrinsic chirp mass of the binary source multiplied by (1 + z), where z is the redshift of the source. Assuming a nonzero cosmological constant, we compute the expected redshift distribution of observed events for an advanced LIGO detector. We find that the redshift distribution has a robust and sizable dependence on the cosmological constant; the data from advanced LIGO detectors could provide an independent measurement of the cosmological constant.

متن کاملGravitational Waves from a Cosmological Distribution of Sources
The advent of gravitational wave detectors such as the Laser Interferometer Space Antenna and the Advanced-Laser Interferometer Gravitational wave Observatory will make it possible to observe many gravitational wave emission phenomena that may or may not have electromagnetic counterparts. In many cases, gravitational waves serve as probes of length and time scales that range many orders of magn...
متن کاملOn gravitational waves in spacetimes with a nonvanishing cosmological constant
We study the effect of a cosmological constant Λ on the propagation and detection of gravitational waves. To this purpose we investigate the linearized Einstein's equations with terms up to linear order in Λ in a de Sitter and an anti-de Sitter background spacetime. In this framework the cosmological term does not induce changes in the polarization states of the waves, whereas the amplitude get...
