Caltech/JPL Association for Gravitational-Wave Research Seminar

Gravitational waves can constitute a unique probe of the primordial universe. In many cases, the characteristic frequency of the emitted GW is directly related to the energy scale at which the GW source is operating: consequently, different GW detectors can probe different energy scales in the evolution of the universe. After a general introduction to the subject, this seminar reviews some of the principal cosmological sources of a stochastic background of GW, and discuss their detection prospects.
