In Albert Einstein's theory of general relativity, space-time becomes dynamic and deformable like the material objects it contains. The theory also reveals the gravity of the geometric properties of space-time. Space-time can deform and even vibrate. We call gravitational waves, the vibrations of space-time. The Gravitation Team of the APC is involved in the direct search of gravitational waves both on the ground (Advanced Virgo) and in space (mission eLISA and its precursor LISA pathfinder). The first direct detection of gravitational waves was recently carried out by the Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, a major result that involves researchers and engineers from the Gravitation team. This marks the beginning of a new astronomy using gravitational radiation as a new means of observing the Universe. Gravitational astronomy will give access to information on massive and dense astrophysical objects such as black holes, neutron stars or dwarf stars that are difficult to access to conventional astronomy (using electromagnetic radiation, light, for example) The Gravitation Team BACON Philippe BARSUGLIA Matteo BAYLE Jean-Baptiste BOUFFANAIS Yann CAPOCASA Eleonora CHASSANDE-MOTTIN Eric (responsible) FAYON Lucille HALLOIN Hubert (Deputy Head) Anthony PLAGNOL Eric PORTER Edward TACCA Matteo Connections MOOC Severity: https://www.futurelearn.com/courses/gravity Gravitational wave detectors and sources (Institute of Astronomy, University of Cambridge): http://rhcole.com/apps/GWplotter/ General public Passport for two infinites The Science of Gravitational Waves in High School (article in English) Games (in English): Black hole hunter; Space-time quest; Black hole pong
