Frédérique Marion (LAPP) : Gravitational waves: First results from the LIGO-Virgo O2 run

Europe/Paris
Description


The advent of advanced detectors truly opened the era of GW astronomy with the first signals from binary black hole mergers detected by Advanced LIGO during the O1 run. The 9-month long O2 run was again very successful, and Advanced Virgo's joining in for the last weeks of O2 was a game changer for source localization. The seminar will provide a review of the results derived from the detections so far, including the spectacular GW170817, the first signal from a binary neutron star coalescence, and its associated electromagnetic counterparts, GRB170817A and AT2017gfo. Prospects for the next few years will be outlined.
