Non-Gaussian Formation of Primordial Black Holes: Effects on the Threshold / Kehagias, Alex (Natl. Tech. U., Athens) ; Musco, Ilia (ICC, Barcelona U.) ; Riotto, Antonio (Geneva U., CAP ; CERN)
Primordial black holes could have been formed in the early universe from sufficiently large cosmological perturbations re-entering the horizon when the Universe is still radiation dominated. These originate from the spectrum of curvature perturbations generated during inflation at small-scales. [...]

The Ineludible non-Gaussianity of the Primordial Black Hole Abundance / De Luca, V. (Geneva U., CAP) ; Franciolini, G. (Geneva U., CAP) ; Kehagias, A. (Natl. Tech. U., Athens) ; Peloso, M. (U. Padua, Dept. Phys. Astron. ; INFN, Padua) ; Riotto, A. (Geneva U., CAP ; CERN) ; Ünal, C. (Rez, Nucl. Phys. Inst.)
We study the formation of primordial black holes when they are generated by the collapse of large overdensities in the early universe. Since the density contrast is related to the comoving curvature perturbation by a nonlinear relation, the overdensity statistics is unavoidably non-Gaussian. [...]

Renormalized Primordial Black Holes / Franciolini, Gabriele (CERN) ; Ianniccari, Andrea (Geneva U.) ; Kehagias, Alex (Geneva U. ; Natl. Tech. U., Athens) ; Perrone, Davide (Geneva U.) ; Riotto, Antonio (Geneva U.)
The formation of primordial black holes in the early universe may happen through the collapse of large curvature perturbations generated during a non-attractor phase of inflation or through a curvaton-like dynamics after inflation. The fact that such small-scale curvature perturbation is typically non-Gaussian leads to the renormalization of composite operators built up from the smoothed density contrast and entering in the calculation of the primordial black abundance.
