Sources of gravitational waves are often expected to be observable
through several messengers, such as gamma rays, X-rays, optical, radio,
and/or neutrino emission. Some of these channels are already being used
in searches for gravitational waves with the LIGO-GEO600-Virgo
interferometer network, and others are currently being incorporated into
new searches. Astrophysical targets include gamma-ray bursts, soft-gamma
repeaters, supernovae, and glitching pulsars. The simultaneous
observation of electromagnetic or neutrino emission could be a crucial
aspect for the first direct detection of gravitational waves.
Information on the progenitor, such as trigger time, direction and
expected frequency range, can enhance our ability to identify
gravitational wave signatures with amplitudes close to the noise floor
of the detector. Furthermore, combining gravitational waves with
electromagnetic and neutrino observations will enable the extraction of
scientific insight that was hidden from us before. I will discuss the
status of detection efforts with the LIGO-GEO600-Virgo network as well
as the science goals and outlook for second and third generation
gravitational wave detectors.
