The Irrelevance of Primordial Black Hole Clustering in the LVK mass range
F. Crescimbeni, V. Desjacques, G. Franciolini +6
We show that in realistic models where primordial black holes are formed due to the collapse of sizeable inflationary perturbations, their initial spatial clustering beyond Poisson…
Why the Universal Threshold for Primordial Black Hole Formation is Universal
Alex Kehagias, Davide Perrone, Antonio Riotto
We show why the threshold for primordial black hole formation is universal (independent from the shape of the perturbation) when expressed in terms of the volume averaged compactio…
The Black Hole Formation -- Null Geodesic Correspondence
Andrea Ianniccari, Antonio J. Iovino, Alex Kehagias +2
We provide evidence for a correspondence between the formation of black holes and the stability of circular null geodesics around the collapsing perturbation. We first show that th…
The Primordial Black Hole Abundance: The Broader, the Better
A. Ianniccari, A. J. Iovino, A. Kehagias +2
We show that the abundance of primordial black holes, if formed through the collapse of large fluctuations generated during inflation and unless the power spectrum of the curvature…
Renormalized Primordial Black Holes
Gabriele Franciolini, Andrea Ianniccari, Alex Kehagias +2
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 o…
