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…
Bouncing completion of eternal inflation
Alexsandre L. Ferreira, Nelson Pinto-Neto, Vanessa N. Xavier
Using a purely kinematical argument, the Borde-Guth-Vilenkin (BGV) theorem states that any maximal space-time with average positive expansion is geodesically incomplete, hence past…
Dynamical analysis of quantum matter bounces with dark sector mimickers
Francisco Bento Lustosa, Nelson Pinto-Neto
We study the effects of the inclusion of fluids In bounce scenarios driven by an exponential potential scalar field. Most solutions exhibit well known tracking behavior between the…
