The very first detection of #GravitationalWaves by ground-based observatories took place in 2015. In less than ten years, the antenna of the European Space Agency’s (#ESA) #LISA space mission will detect waves in the millihertz frequency band, which remains unexplored to this day. This will lead to the discovery of new #sources, both gigantic and distant...

John Baker (L2IT, Toulouse) will give Irapiens a preview of the observations planned by LISA this Thursday: https://www.irap.omp.eu/event/listening-to-the-millihertz-universe-with-the-laser-interferometer-space-antenna-lisa/

La toute première détection des #OndesGravitationnelles par des observatoires terrestres date de 2015. Dans moins de dix ans, l'antenne de la mission spatiale #LISA de l'European Space Agency - ESA capturera des ondes dans la bande de fréquences millihertz, inexplorée à ce jour. S'ensuivra la découverte de nouvelles #sources, gigantesques et lointaines à la fois ...
