Observational results from the LIGO and Virgo detectors

Abstract : The first generation of ground-based interferometric gravitational wave detectors, LIGO, GEO and Virgo, have operated and taken data at their design sensitivities over the last few years. The data have been examined for the presence of gravitational wave signals. While no gravitational wave events have been found important astrophysical statements can be made. The most significant results are presented in this article. The network of detectors is currently being upgraded and extended. This upgrade will provide the sensitivity needed for the direct detection of an astrophysical source emitting gravitational waves. For instance, the binary neutron stars inspiral distance range will reach 200 Mpc when upgraded detectors reach their design sensitivities circa 2020. The capability of the global network to determine accurately the sky location of the source is opening a new window on the Universe, where gravitational alerts will be used for quick electro-magnetic follow-ups of the sources.
