Phys. Rev. D 55, 3260–3264 (1997)Detecting relic gravitational radiation from string cosmology with LIGOReceived 4 September 1996; published in the issue dated 15 March 1997 A characteristic spectrum of relic gravitational radiation is produced by a period of “stringy inflation” in the early Universe. This spectrum is unusual, because the energy density rises rapidly with frequency. We show that correlation experiments with the two gravitational-wave detectors being built for the Laser Interferometric Gravitational Wave Observatory could detect this relic radiation for certain ranges of the parameters that characterize the underlying string cosmology model. © 1997 The American Physical Society URL:
