The LIGO observatories are built and operated by the LIGO Laboratory (California Institute of Technology and Massachusetts Institute of Technology) with participation by the LIGO Scientific Collaboration, and are supported by the U.S. National Science Foundation. The Virgo detector is designed, built and operated by a collaboration that includes the Centre National de la Recherche Scientifique (France), the Istituto Nazionale di Fisica Nucleare (Italy) and Nikhef (Netherlands), with Polish, Hungarian and Spanish institutes and the European Gravitational Observatory (EGO) consortium.
