Cosmological parameters from lenses distance ratio
Vincenzo F. Cardone, Ester Piedipalumbo, Paolo Scudellaro
Strong lensing provides popular techniques to investigate the mass distribution of intermediate redshift galaxies, testing galaxy evolution and formation scenarios. It especially p…
High Redshift Investigation On The Dark Energy Equation of State
E. Piedipalumbo, E. Della Moglie, M. De Laurentis +1
The understanding of the accelerated expansion of the Universe poses one of the most fundamental questions in physics and cosmology today. Whether or not the acceleration is driven…
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…
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…
