Browsing: Virgo Collaboration

The Virgo Collaboration is an international scientific effort focused on the direct detection of gravitational waves and the development of gravitational-wave astronomy as a tool for understanding the cosmos. The collaboration operates the Virgo interferometer, a large-scale laser interferometer located near Pisa, Italy, designed to detect gravitational waves emitted by cosmic events such as merging black holes and neutron stars. Established in the 1990s, the collaboration includes researchers from numerous European countries and works in close partnership with other observatories around the world, including the U.S.-based LIGO (Laser Interferometer Gravitational-Wave Observatory). The detection of gravitational waves, first achieved by LIGO in 2015 and subsequently by Virgo, has opened a new window onto the universe, providing insights into phenomena that are invisible in ordinary electromagnetic observations and enabling tests of general relativity under extreme conditions.
