Non-Gaussian formation of primordial black holes
A. Kehagias, Ilia Musco, Antonio Riotto
Izvirni znanstveni članek
Oznake: cosmological perturbation theory;non-Gaussianity;primordial black holes;
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. Beca ...

Threshold for primordial black holes
Ilia Musco, Valerio De Luca, Gabriele Franciolini, Antonio Riotto
Izvirni znanstveni članek
Oznake: primordial black holes;threshold prescription;curvature perturbation;
Primordial black holes could have been formed in the early universe from nonlinear cosmological perturbations reentering the cosmological horizon when the Universe was still radiation dominated. Starting from the shape of the power spectrum on superhorizon scales, we provide a simple prescription, b ...
