No compelling cosmological models come out of magnetic universes which are based in nonlinear electrodynamics
Ricardo Garcia-Salcedo, Tame Gonzalez, Israel Quiros
Here we investigate the cosmic dynamics of Friedmann-Robertson-Walker universes -- flat spatial sections -- which are driven by nonlinear electrodynamics (NLED) Lagrangians. We pay…
Comment on "Extended Born-Infeld theory and the bouncing magnetic universe"
Ricardo Garcia-Salcedo, Tame Gonzalez, Israel Quiros
In a recent paper [Phys. Rev. D{\bf 85}, 023528 (2012)] the authors proposed a generalized Born-Infeld electrodynamics coupled to general relativity which produces a nonsingular bo…
Bulk Viscous Matter-dominated Universes: Asymptotic Properties
Arturo Avelino, Ricardo Garcia-Salcedo, Tame Gonzalez +2
By means of a combined use of the type Ia supernovae and H(z) data tests, together with the study of the asymptotic properties in the equivalent phase space - through the use of th…
QCD ghost dark energy cannot (even roughly) explain the main features of the accepted cosmological paradigm
Ricardo Garcia-Salcedo, Tame Gonzalez, Israel Quiros +1
We explore the whole phase space of the so called Veneziano/QCD ghost dark energy models where the dynamics of the inner trapping horizon is ignored and also the more realistic mod…
