Cosmology with Gravitational Waves

by Chiara Caprini (CEA Saclay)

Europe/Brussels
Description

Gravitational wave observations have the potential to probe cosmology. This talk presents two observables through which GW detection could provide us with new information on the characteristics of the universe, complementary to what can be gathered from electromagnetic observations: the detection of a stochastic background of gravitational waves coming from the very early universe, and the use of compact binaries as standard sirens to test the expansion of the universe.
