Scalar field description of a parametric model of dark energy

E. M. Barboza, J. S. Alcaniz, B. Santos

We investigate theoretical and observational aspects of a time-dependent parameterization for the dark energy equation of state (EoS) $w (z)$ , which is a well behaved function of th…

Probing the time dependence of dark energy

E. M. Barboza, J. S. Alcaniz

A new method to investigate a possible time-dependence of the dark energy equation of state $w$ is proposed. We apply this methodology to two of the most recent data sets of type I…
