The Gravitational Universe

What is Virgo?

Virgo is a giant laser interferometer designed to detect gravitational waves for the first time. It is now operated and improved in Cascina, near Pisa on the site of the European Gravitational Observatory (EGO), by an international collaboration of scientists from France, Italy, the Netherlands, Poland, and Hungary.

The Gravitational Universe

Today we study the universe mainly by observing visible light and other forms of electromagnetic radiation, such as radio waves, X rays, and gamma rays. However, recently we started exploiting other cosmic “messengers”, such as cosmic rays, neutrinos and gravitational waves.

Frontier Technology

The detection of gravitational waves is an extremely difficult task: the expected signals are extremely faint and measurements are affected by many different kind of noise. This is a typical situation in many experiments in modern Physics, and Virgo is no exception. Advanced Virgo is based on modern, cutting-edge technologies.

The first Fused Silica monolithic suspension for Advanced Virgo

Thermal noise in mirror suspension is the most severe limit to the low-frequency sensitivity of first generation interferometric gravitational wave detectors. To minimize the pendulum thermal noise, a monolithic suspension, using fused silica as a low dissipation material, has been developed for Advanced Virgo. Now the first monolithic suspension has been realized last Thursday June 11st, thanks to a strong collaboration between the INFN groups of Perugia, Firenze and Roma1.
