Abstract: (IOP) The first observation of a binary neutron star (NS) coalescence by the Advanced LIGO and Advanced Virgo gravitational-wave (GW) detectors offers an unprecedented opportunity to study matter under…
Abstract: (APS) Cosmic strings are topological defects which can be formed in grand unified theory scale phase transitions in the early universe. They are also predicted to form in the…
Press release Scientific paper: GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral
Abstract: (APS) On August 14, 2017 at 10∶30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coalescence of…
On the 11th of February 2016, the Virgo and LIGO collaboration announced the first detection of a gravitational wave. It has been produced by a system of two black holes…
Abstract: On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from…
In 2015, Patrice Hello and the Virgo-LAL group were rewarded by the grand prix scientifique de la Fondation Simone et Cino Del Duca. For this occasion, the group went to…
Abstract: (IOP) The production of a primordial stochastic gravitational-wave (GW) background by processes occuring in the early Universe is expected in a broad range of models. Observing this background would…
Abstract The thermally deformable mirror is a device aiming at correcting beam-wavefront distortions for applications where classical mechanical methods are precluded by noise considerations, as in advanced gravitational wave interferometric…
