Abstract
Interferometric gravitational wave detectors could measure the frequen cy sweep of a binary inspiral (characterized by its chirp mass) to hig h 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 sou rce. Assuming a nonzero cosmological constant, we compute the expected redshift distribution of observed events for an advanced LIGO detecto r. We find that the redshift distribution has a robust and sizable dep endence on the cosmological constant; the data from advanced LIGO dete ctors could provide an independent measurement of the cosmological con stant.
