Description

Abstract: 

Primordial Black Holes (PBHs) can form from large enhancement of primordial curvature perturbations during early epoch of the universe. In this talk, I will investigate the scenario where such large curvature perturbations are produced in a double inflationary model. Furthermore, by using the current GWTC-3 data, I will reconstruct the primordial curvature perturbations on small scales, which shows the consistency of PBH formation scenario.
