Gravity

Physical properties of Spacetime are investigated directly by means of observatories of Gravitational Waves. My group at SISSA is involved in one of the main global efforts for measuring the gravitational emission from Space. See here for more detailed information available at SISSA.

The Laser Interferometer Space Antenna (LISA) will be the first space based observatory of Gravitational Waves (GWs). Selected to be third large class mission of the European Space Agency (ESA), it will consist of three spacecraft separated by 2.5 million km in a triangular formation, following Earth in its orbit around the Sun. Launch is expected in 2037. LISA will investigate GWs generated through collision of compact objects, dynamics of supermassive Black Holes, and physics of the Early Universe. The project is led by the ESA, in collaboration with the National Aeromautics and Space Administration, and an international consortium of scientists.
