2 large interferometers, Virgo, and GEO (located near Hannover) and three cryogenic
(below liquid Helium temperature) resonant antennas located at CERN, Frascati
and Legnaro, Europe is at the forefront of research on gravitational waves.
More than 20 laboratories and a few hundred researchers in 6 European countries
are already involved in experimental developments aiming at gravitational waves
detection. A large number of theoretical physicists and astrophysicists are
also involved in the prediction of gravitational waves sources characteristics
and in the analysis of experimental data.
Future resonant detectors may use spheres instead of bars. They could usefully
complement the network of interferometers.
