Physique des ondes gravitationnelles (en)

The UCLouvain gravitational-wave (GW) group contributes to the global effort to detect GWs in order to study gravity and the universe. We are active in all aspects of gravitational-wave science including astronomy, data analysis, computing, laser optics & opto-mechatronics. The group is part of the international scientific Collaboration Virgo, an operating GW detector at the European Gravitational Observatory (EGO), and Einstein Telescope (ET), a planned GW observatory that could be built at the border region between Belgium, the Netherlands and Germany. Our group, in collaboration with laser physicists outside CP3, is active in instrumentation projects for both Virgo and ET making use of the UCLouvain laser & optics technological platform and two international research and development facilities E-TEST and ETPF. The UCLouvain GW group is also active in data analysis of the LIGO/Virgo/KAGRA detectors and develops new data analysis techniques for ET. The data analysis studies, many of which are performed in collaboration with theoretical physicists and applied mathematics engineers outside CP3, make use of the CP3 computing center. Finally, our group is also giving important contributions to the development of the computing infrastructure of Virgo and ET.
