Primordial Black Hole Formation from Type II Fluctuations with Primordial Non-Gaussianity
Masaaki Shimada, Albert Escrivá, Daiki Saito +2
This study investigates the formation of primordial black holes (PBHs) resulting from the collapse of adiabatic fluctuations with large amplitudes and non-Gaussianity. Ref. \cite{U…
Simulations of Ellipsoidal Primordial Black Hole Formation
Albert Escrivà, Chul-Moon Yoo
We perform relativistic numerical simulations to study primordial black hole (PBH) formation from the collapse of adiabatic super-horizon non-spherical perturbations generate…
Non-spherical effects on the mass function of Primordial Black Holes
Albert Escrivà, Chul-Moon Yoo
In this letter, we investigate the impact of non-spherical effects on the Primordial Black Hole mass function, based on the ellipticity-dependent threshold calculated by performing…
The LISA forecast on a smooth crossover beyond the Standard Model through the scalar-induced gravitational waves
Albert Escrivà, Ryoto Inui, Yuichiro Tada +1
Supposing the Laser Interferometer Space Antenna (LISA) gravitational wave (GW) detector, we exhibit the detectability of a hypothetical smooth crossover in the early universe beyo…
Were you born in an aborted primordial black hole?
Emilie Despontin, Sebastien Clesse, Albert Escrivà +1
We propose a mechanism of electroweak baryogenesis based on the Standard Model and explaining the coincidence between the baryon and Dark Matter (DM) densities. Large curvature flu…
Numerical simulation of type II primordial black hole formation
Koichiro Uehara, Albert Escrivà, Tomohiro Harada +2
This study investigates the formation of type II primordial black holes (PBHs) resulting from extremely large amplitudes of initial fluctuations in a radiation-dominated universe.…
