Prospects for Stochastic Background Searches Using Virgo and LSC Interferometers [PDF]
, 2007 We consider the question of cross-correlation measurements using Virgo and the LSC Interferometers (LIGO Livingston, LIGO Hanford, and GEO600) to search for a stochastic gravitational-wave background. We find that inclusion of Virgo into the network will
