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 formation from spherically symmetric hydrodynamical perturbations: a review
Albert Escrivà
Primordial black holes, which could have been formed in the very early Universe due to the collapse of large curvature fluctuations, are nowadays one of the most attractive and fas…
Effects of the shape of curvature peaks on the size of primordial black holes
Albert Escrivà, Antonio Enea Romano
We simulate numerically the formation of spherically symmetric primordial black holes (PBHs) seeded by different families of primordial curvature perturbations profiles on a Friedm…
Analytical thresholds for black hole formation in general cosmological backgrounds
Albert Escrivà, Cristiano Germani, Ravi K. Sheth
We consider black holes which form from an initially spherically symmetric super-Hubble perturbation of a cosmological background filled by a perfect fluid with $w\in (0,1]…
