Primordial Black Hole Formation during a Strongly Coupled Crossover
Albert Escrivà, Javier G. Subils
The final mass distribution of primordial black holes is sensitive to the equation of state of the Universe at the scales accessible by the power spectrum. Motivated by the presenc…
Simulations of PBH formation at the QCD epoch and comparison with the GWTC-3 catalog
Albert Escrivà, Eleni Bagui, Sebastien Clesse
The probability of primordial black hole (PBH) formation is known to be boosted during the Quantum Chromodynamics (QCD) crossover due to a slight reduction of the equation of state…
Simulation of Primordial Black Holes with large negative non-Gaussianity
Albert Escrivà, Yuichiro Tada, Shuichiro Yokoyama +1
In this work, we have performed numerical simulations of primordial black hole (PBH) formation in the Friedman-Lemaître-Robertson-Walker universe filled by radiation fluid, introdu…
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…
