The out-state of scalar-induced gravitational waves
Year: 2026
Type: preprint
Abstract: Scalar-induced gravitational waves (SIGWs) are described by second-order tensor perturbations that contain free radiation together with a gauge-dependent response maintained by the scalar source. For a perfect fluid with constant equation of state $0
