Description

After several years of construction and commissioning, LIGO, GEO600 and Virgo gravitational waves detectors have reached or exceeded their foreseen sensitivities and are in operation for few years. Even if a first detection remains unlikely with these sensitivities, meaningful results from the astrophysical point of view have been obtained on gamma-ray bursts or pulsars for example. For the current joint scientific run of LSC and Virgo collaborations, the "multi-messenger" approach has reached maturity and, in particular, online searches have been implemented in order to trigger external observations by satellites or telescopes. We hope that this "multi-messenger" strategy will be fruitful when the next generation of detectors will perform their first science runs in 2015. With a sensitivity increased by a factor 10, gravitational wave events should become frequent and will allow a better understanding of the source physics.
