High redshift cosmography: new results and implication for dark energy
Marek Demianski, Ester Piedipalumbo, Claudio Rubano +1
The explanation of the accelerated expansion of the Universe poses one of the most fundamental questions in physics and cosmology today. If the acceleration is driven by some form…
On exact solutions for quintessential (inflationary) cosmological models with exponential potentials
Ester Piedipalumbo, Paolo Scudellaro, Giampiero Esposito +1
We first study dark energy models with a minimally-coupled scalar field and exponential potentials, admitting exact solutions for the cosmological equations: actually, it turns out…
Noether symmetry for Gauss-Bonnet dilatonic gravity
Abhik Kumar Sanyal, Claudio Rubano, Ester Piedipalumbo
Noether symmetry for Gauss-Bonnet-Dilatonic interaction exists for a constant dilatonic scalar potential and a linear functional dependence of the coupling parameter on the scalar…
A matter-dominated cosmological model with variable and . Confrontation of theoretical predictions with observational data
Ester Piedipalumbo, Paolo Scudellaro, Giampiero Esposito +1
In the framework of renormalization-group improved cosmologies, we analyze both theoretically and observationally the exact and general solution of the matter-dominated cosmologica…
The GRBs Hubble diagram in quintessential cosmological models
Marek Demianski, Ester Piedipalumbo, Claudio Rubano
It has been recently empirically established that some of the directly observed pa- rameters of GRBs are correlated with their important intrinsic parameters, like the luminosity o…
On the transition from complex to real scalar fields in modern cosmology
Giampiero Esposito, Raju Roychowdhury, Claudio Rubano +1
We study some problems arising from the introduction of a complex scalar field in cosmology, modelling its possible behaviors in both the inflationary and dark energy stages of the…
