Constraints on primordial curvature spectrum from primordial black holes and scalar-induced gravitational waves

Yi, Zhu; Fei, Qin

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 models that can produce primordial black holes, such as nonm…
