Cosmology with gravitational wave detection

10.03.2017 14:15 – 15:00

After the direct observation of gravitational waves performed by the aLIGO/Virgo col- laboration, and in preparation to the space-based interferometer LISA, it is now timely to investigate how gravitational waves can be exploited as a new mean to probe the uni- verse, other than electromagnetic radiation and neutrinos. Gravitational wave detection, in fact, has the potential to be a powerful test for cosmology and the early universe. This talk introduces two observables through which one could gather new information on the characteristics of the universe: namely, the detection of a stochastic background of gravi- tational waves coming from the early universe, and the use of massive black hole binaries as ’standard sirens’, to test the expansion of the universe.
