Isotropy, anisotropies and non-Gaussianity in the scalar-induced gravitational-wave background: diagrammatic approach for primordial non-Gaussianity up to arbitrary order
Jun-Peng Li, Sai Wang, Zhi-Chao Zhao +1
Produced nonlinearly by the enhanced linear cosmological curvature perturbations, the scalar-induced gravitational waves (SIGWs) can serve as a potentially powerful probe of primor…
Isotropic background and anisotropies of gravitational waves induced by cosmological soliton isocurvature perturbations
