Gravitational waves and cosmology: the potential of the LISA observatory

This talk presents two observables through which gravitational wave 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 early universe, and the use of compact binaries as standard sirens to test the expansion of the universe. In particular, we will focus on the potential of the Laser Interferometer Space Antenna, the gravitational wave observatory to be launched by the European Space Agency in the early 2030s.
