Analysis of two quintessence models with SN Ia data

Astrophysics 2009-11-06 v2

Abstract

The supernovae Ia data are used to analyze two general exact solutions for quintessence models. The best fit values for Ωm0\Omega_{m0} are smaller than in the Λ\Lambda -term model, but still acceptable. With present-day data, it is not possible to discriminate among the various situations.
