Abstract

We classify dark energy models in a plane of observables that correspond to the common parameterization of a non-constant equation of state, w(a) = w 0 + w a (1 − a), where a is the scale factor of the universe. The models fall into four classes and only two of these classes have a region of overlap in the observable plane. We perform a joint analysis of… (More)
