PBH in single field inflation: the effect of shape dispersion and non-Gaussianities
Vicente Atal, Judith Cid, Albert Escrivà +1
Primordial black holes (PBHs) may result from high peaks in a random field of cosmological perturbations. In single field inflationary models, such perturbations can be seeded as t…

Primordial black hole formation with non-Gaussian curvature perturbations
Vicente Atal, Jaume Garriga, Airam Marcos-Caballero
In the context of transient constant-roll inflation near a local maximum, we derive the non-perturbative field redefinition that relates a Gaussian random field with the true non-G…
