The Implications of the Microwave Background Anisotropies for Laser-Interferometer-Tested Gravitational Waves

Abstract

The observed microwave background anisotropies in combination with the theory of quantum mechanically generated cosmological perturbations predict a well measurable amount of relic gravitational waves in the frequency intervals tested by LISA and ground-based laser interferometers.
