Gravitational radiation

The potential cosmological sources of gravitational radiation and the detectors used to measure it are discussed, surveying the current status of investigations. Detectors characterized include room-temperature and cryogenic bars, torsion pendula, laser interferometric detectors, and space-based detectors. The sources are supernovae (e.g., SN 1987A) and gravitational collapses, coalescing compact-object binaries, pulsars, Wagoner stars, the stochastic background, and LF sources (black-hole formation in galactic centers, Galactic binaries, and stars falling into nearby black holes). Also considered are outstanding theoretical modeling problems with implications for gravitational-wave observations. 46 refs
