Primordial Black Hole Formation in Dust-Radiation Bouncing Cosmologies
Xuan Ye, Luiz Felipe Demetrio, Eduardo Jose Barroso +2
Primordial black holes (PBHs) provide a unique probe of the early Universe and may have an enhanced abundance in bouncing cosmologies, where a long contracting phase can amplify pe…
Two Fluid Quantum Bouncing Cosmology I: Theoretical Model
Sandro D. P. Vitenti, Nelson Pinto-Neto, Patrick Peter +1
Bouncing cosmologies offer an alternative to inflation by resolving the initial singularity through a contracting phase followed by a bounce into expansion. In many such models, th…
Primordial Black Hole Formation in a Dust Bouncing Model
E. J. Barroso, L. F. Demétrio, S. D. P. Vitenti +1
Linear scalar cosmological perturbations have increasing spectra in the contracting phase of bouncing models. We study the conditions for which these perturbations may collapse int…
