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) , which is a well behaved function of th…

Thermodynamics and dark energy
R. Silva, R. S. Goncalves, J. S. Alcaniz +1
A significant observational effort has been directed to unveil the nature of the so-called dark energy. However, given the large number of theoretical possibilities, it is possible…

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 is proposed. We apply this methodology to two of the most recent data sets of type I…
