Gravitational wave emission from the CMB and other thermal fields

Gravitational wave emission from the CMB and other thermal fields

We calculate the gravitational wave power density emitted by quantum thermal sources. As particular cases, we calculate the emission of gravitational waves from the cosmic microwave background and from stellar sources. We study how treating gravity classically affects the prediction of the thermal e...
