Gravitational waves, a new light from the Universe
Abstract
Gravitational waves are a consequence of the General Theory of Relativity, formulated by Albert Einstein in 1916. This theory states that the presence of mass changes the geometry of space time, making it curved. When accelerated masses move, the geometry changes have to propagate into the whole volume, by means of gravitational waves.
Evidence of gravitational waves has been found in a few astrophysical binary systems, whose motion can be explained only with the emission of gravitational waves. However the effect of these waves is so tiny that no instrument has been able to detect them: the distance between two masses separated by 1 m has to be measured at the level of 10-21 m!
Gravitational waves carry information on the mass motion in violent astrophysical events like SN explosion, creation of black holes. They interact so weakly that they can cross undisturbed the whole Universe. So they let us “see” behind opaque dust clouds, inside stars, or probe the first moments of the Big Bang, as a new light from the Universe.
In the presentation the experimental challenges will be described, as well as the current effort by very large projects to build sensitive instruments. Expected sources will be described, also in connection with the possibility of observing simultaneously gravitational waves, light, radio pulses, high energy photons and neutrinos, starting a new astronomy.
17:30Reception hosted by the ambassador Vincenzo PETRONE
Ambasciata d’Italia, 2-5-4 Mita, Minato-ku , Tokyo
In the evening of 3 October, a delegation of the participants in the EGO-ICRR Workshop (Profs. Takaaki Kajita, Federico Ferrini, Francesco Fidecaro, Riccardo De Salvo) will join a meeting with the italian Vice-Minister of Foreign Affairs H.E. Stefania Craxi and the Ambassador of Italy to Japan, H.E. Vincenzo Petrone, at the Italian Embassy in Tokyo. This event will be the occasion to present the ongoing and future cooperation projects between EGO and ICRR.
EGO-ICRR Meeting
University of Tokyo, Kashiwa campus, Japan, 4-5 October 2011
The European Gravitational Observatory (EGO) and the Institute for Cosmic Ray Research (ICRR) organize a meeting, under the patronage of the Italian Embassy in Tokyo, with the aim to explore the collaboration between Italy and Japan on the Gravitational Wave research with the future interferometric detectors in Italy (advanced Virgo) and Japan (LCGT). The 3rd generation perspectives, thanks to the Einstein Telescope (ET) project will be investigated too and the ELiTES Japanese-European collaborative FP7 project, between ET and LCGT, will be prepared.
