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…
Communiqué de presse Publication scientifique: 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…
Mercredi 27 septembre 2017, les collaborations LIGO et Virgo ont annoncé en marge du sommet «G7 Science» à Turin une quatrième détection d’une fusion de deux trous noirs. Le signal…
Le 11 Février 2016, les collaborations LIGO et Virgo annoncent la première détection d'ondes gravitationnelles. Celles-ci ont été produites par un système de deux trous noirs et détectées sur Terre…
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…
En 2015, Patrice Hello et le groupe Virgo-LAL ont reçu le grand prix scientifique de la Fondation Simone et Cino Del Duca. A cette occasion, le groupe s'est rendu à…
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…
