Cosmic voids in modified gravity scenarios
E L D Perico, R Voivodic, M Lima +1
Modified gravity (MG) theories aim to reproduce the observed acceleration of the Universe by reducing the dark sector while simultaneously recovering General Relativity (GR) within…
Running Vacuum Cosmological Models: Linear Scalar Perturbations
E. L. D. Perico, D. A. Tamayo
In cosmology, phenomenologically motivated expressions for running vacuum are commonly parametrized as linear functions or . Such kind of models assume an equation o…
Complete Cosmic History with a dynamical Lambda(H) term
E. L. D. Perico, J. A. S. Lima, Spyros Basilakos +1
In the present mainstream cosmology, matter and spacetime emerged from a singularity and evolved through four distinct periods: early inflation, radiation, dark matter and late-tim…
Reproducing neutrino effects on the matter power spectrum through a degenerate Fermi gas approach
E. L. D. Perico, Alex E. Bernardini
Modifications on the predictions about the matter power spectrum based on the hypothesis of a tiny contribution from a degenerate Fermi gas (DFG) test-fluid to some dominant cosmol…
Degenerate Fermi gas perturbations at standard background cosmology
Alex E. Bernardini, E. L. D. Perico
The hypothesis of a tiny fraction of the cosmic inventory evolving cosmologically as a degenerate Fermi gas test fluid at some dominant cosmological background is investigated. Our…
