Titre | Ground based gravitational-wave astronomy in the next decades |
Résumé | After the first gravitational wave detection in 2015 and the GW170817 multi-messenger observation, the gravitational-wave astronomy has evolved rapidly. LIGO and Virgo detectors have performed their 3rd observing run between April 2019 and March 2020 and the third catalog of gravitational-waves sources (GWTC-3) has just been released, with a total of 90 sources detected so far. Upgrades of LIGO and Virgo are planned in the decade 2020-2030, increasing the scientific potential of the gravitational-wave detector network, which will include two more instruments in the next years: KAGRA in Japan and a third LIGO in India. In the decade 2030, the Einstein Telescope project, an European underground gravitational-wave observatory, aims to increase the sensitivity of current detector by one order of magnitude. In this seminar, after an summary about the current gravitational-wave observations, I will be describe in detail the LIGO-Virgo plans for the 2020 decade and then the scientific objectives and plans for Einstein Telescope. Matteo Barsuglia, directeur de recherche au CNRS (au laboratoire Astroparticule et Cosmologie), responsable pour la France de Virgo et Einstein Telescope. |
