CB damping of primordial gravitational waves and the fine-tuning of the CB temperature anisotropy
Alex E. Bernardini, Jonas F. G. Santos
Damping of primordial gravitational waves due to the anisotropic stress contribution owing to the cosmological neutrino background (CB) is investigated in the context of a radia…
Cosmological neutrino entropy changes due to flavor statistical mixing
Alex E. Bernardini
Entropy changes due to delocalization and decoherence effects should modify the predictions for the cosmological neutrino background (CB) temperature when one treats neutrino fl…
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…
Dynamical neutrino masses in the generalized Chaplygin gas scenario with mass varying CDM
Alex E. Bernardini
Neutrinos coupled to an underlying scalar field in the scenario for unification of mass varying dark matter and cosmon-{\em like} dark energy is examined. In the presence of a tiny…
Equilibrium and stability of neutrino lumps as TOV solutions
Alex E. Bernardini
We report about stability conditions for static, spherically symmetric objects that share the essential features of mass varying neutrinos in cosmological scenarios. Compact struct…
