Constraints on primordial curvature spectrum from primordial black holes and scalar-induced gravitational waves
Abstract The observational data of primordial black holes and scalar-induced gravitational waves can constrain the primordial curvature perturbation at small scales. We parameterize the primordial curvature perturbation by a broken power law form and find that it is consistent with many inflation mo...
