The international collaborators will comment on their ongoing research, at their first press conference since the historic observation of gravitational waves.

100 years after Einstein predicted the existence of gravitational waves, the European Gravitational Observatory (EGO) and the VIRGO Collaboration invite the scientific community at the EGO site in Cascina, Pisa (Italy) for an update on efforts to detect them. Cascina (Pisa, Italy) – Journalists are invited to join the site of the European Gravitational […]
From the 24th to the 27th of September, a green colored laser has done a
round trip between the Basilica of Notre-Dame de Fourvière and the city
hall of Vaulx en Velin, 7 km away. Thanks to a simple rotating mirror,
it has been possible for people to measure the speed of light.
È stato siglato il 18 settembre l’accordo tra INFN e CNRS, per il rinnovo di altri cinque anni del consorzio italo-francese EGO (European Gravitational Observatory), che gestisce l’esperimento VIRGO
Venerdì 25 e sabato 26 settembre l’Osservatorio Gravitazionale Europeo (EGO) aprirà le porte al grande pubblico nell’ambito degli eventi legati alla Notte Europea dei Ricercatori 2015. Nel corso delle due giornate sarà possibile visitare l’esperimento Virgo per la ricerca delle onde gravitazionali e partecipare a spettacoli, conferenze, osservazioni astronomiche, e attività per i più piccoli.
The first Advanced Virgo test mass has been installed at the input of the east-west arm of Virgo. This milestone represents a remarkable achievement: the new payload integrates several key technologies and has been regarded as of the main technical challenges of the project.
What is a scientist? How is the typical day of a scientists? What are the main goals of Virgo? These are some of the questions that students ask to us very frequently. That is why at EGO we decided to organize a special meeting with the local high schools of Pisa and tell them what is the life of a scientists.
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.
In Virgo, we use light as a tool to measure the spacetime and detect gravitational waves. That is why the scientists of Virgo participated in the Global Open Lab Days (GOLD) initiative promoted by the committee of the International Year of Light (IYL2015).
