Single field matter bounce with dark energy era: comparison with CMB Planck 2018 data and best fit parameters
Rodrigo F. Pinheiro, Nelson Pinto-Neto
In this work, we perform Markov Chain Monte Carlo (MCMC) analyses using the Planck 2018 cosmic microwave background (CMB) datasets, including temperature, polarization, and lensing…
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…
