Dynamics of Primordial Black Hole Formation
Primordial overdensities seeded, for instance, by inflation or topological defects may collapse to primordial black holes (PBHs) during early radiation-dominated eras if they exceed a critical threshold [1,2]. This particular PBH formation process, which is examined in this paper, occurs when an initially super-horizon size region of order unity overdensity crosses into the horizon and recollap...
متن کاملPrimordial Black Hole Formation from Inflaton
Measurements of the distances to SNe Ia have produced strong evidence that the Universe is really accelarating, implying the existence of a nearly uniform component of dark energy with the simplest explanation as a cosmological constant. In this paper a small changing cosmological term is proposed, which is a function of a slow-rolling scalar field, by which the de Sitter primordial black holes...
متن کاملPrimordial Black Hole Formation in Supergravity
We study a double inflation model (a preinflation + a new inflation) in supergravity and discuss the formation of primordial black holes which may be identified with massive compact halo objects (MACHOs) observed in the halo of our galaxy. The preinflation drives an inflaton for the new inflation close to the origin through supergravity effects and the new inflation naturally occurs. If the tot...
متن کاملPrimordial Black Hole Baryogenesis
We reconsider the possibility that the observed baryon asymmetry was generated by the evaporation of primordial black holes that dominated the early universe. We present a simple derivation showing that the baryon asymmetry is insensitive to the initial black hole density and the cosmological model but is sensitive to the temperature-dependence of the CP and baryon-violating (or lepton-violatin...
متن کاملNumerical investigation of the threshold for primordial black hole formation
First results of a numerical investigation of primordial black hole formation in the radiation dominated phase of the Early Universe are presented. The simulations follow the gravitational collapse of three different families of high-amplitude density fluctuations imposed at the time of horizon crossing. The threshold for black hole formation, δc ≈ 0.7, is found to be nearly identical for all p...
