Chiara Caprini (APC Paris) - Cosmology with LISA

Vendredi 30 novembre 11:00-12:00

Gravitational waves can constitute a unique probe of both the early and late-time universe. After a general introduction to the subject, this seminar focuses on the potential of the space-based interferometer LISA to test cosmology. In particular, two aspects will be discussed : the stochastic gravitational wave background generated by sources in the very early universe, and the use of compact binaries, emitting gravitational waves, as standard sirens, i.e. to probe the energy content and the acceleration of the late-time universe.
