Memoirs of the curvaton: non-perturbative non-Gaussianity and supermassive primordial black holes
S. Allegrini, A. J. Iovino, G. Perna +1
The curvaton provides a simple mechanism for generating strongly non-Gaussian curvature perturbations after inflation, with potentially important consequences on small scales. We s…
Beware of the running when producing heavy primordial black holes
Sasha Allegrini, Antonio J. Iovino, Hardi Veermäe
We examine single-field inflationary models for the formation of primordial black holes (PBHs). By analyzing the latest observations from the Atacama Cosmology Telescope (ACT)~\cit…
Is the formation of primordial black holes from single-field inflation compatible with standard cosmology?
Sasha Allegrini, Loris Del Grosso, Antonio J. Iovino +1
In this work, we investigate the generation of primordial black holes (PBHs) within the framework of single-field inflationary models and their compatibility with the cosmological…
