On the Stability of Dark Energy Scalar Field Reconstruction from SNe Ia Data
Arpine Piloyan, Sergey Pavluchenko
The current paper addresses the possibility of Dark Energy scalar field potential reconstruction from SNe Ia data and the problems arising during the process. We describe the metho…
Limits on the Reconstruction of a Single Dark Energy Scalar Field Potential from SNe Ia Data
Arpine Piloyan, Sergey Pavluchenko, Luca Amendola
In this paper we perform a reconstruction of the scalar field potential responsible for cosmic acceleration using SNe Ia data. After describing the method, we test it with real SNe…
Linear Perturbation constraints on Multi-coupled Dark Energy
Arpine Piloyan, Valerio Marra, Marco Baldi +1
The Multi-coupled Dark Energy (McDE) scenario has been recently proposed as a specific example of a cosmological model characterized by a non-standard physics of the dark sector of…
Supernova constraints on Multi-coupled Dark Energy
Arpine Piloyan, Valerio Marra, Marco Baldi +1
The persisting consistency of ever more accurate observational data with the predictions of the standard LCDM cosmological model puts severe constraints on possible alternative sce…
