Gravitational Waves and high energy phenomena

In the following years several giant laser interferometers dedicated to gravitational wave detection will be fully operational near their design sensitivity. Analysis combining all the detectors will improved sky coverage and allow meaningful network analysis, providing source location indications. We focus on plausible astrophysical sources and the informations that could be extracted from gravitational wave signal. Observation of gravitational waves would give exclusive insights on source details, from constraints on the equation of state to source dynamics of compact objects. Richer analysis could be expected in case of multi-messenger observations. These have been considered for supernovae, but should be investigated further, including for other phenomena.
