# Cosmological backgrounds of gravitational waves

@article{Caprini2018CosmologicalBO, title={Cosmological backgrounds of gravitational waves}, author={Chiara Caprini and Daniel G. Figueroa}, journal={Classical and Quantum Gravity}, year={2018} }

Gravitational wave observations have a great potential for probing cosmology. Here we concentrate on the early universe, and review proposed sources that can lead to cosmological backgrounds of gravitational waves, many of them within the reach of near-future gravitational wave detectors. We start by defining gravitational waves in a cosmological setting and presenting the reasons why early universe sources give rise to stochastic gravitational wave backgrounds. We recap the current…
