Dark energy reconstruction based on the Padé approximation; an expansion around the $$\varLambda $$ Λ CDM
Abstract We study the dynamical properties of dark energy based on a large family of Padé parameterizations for which the dark energy density evolves as the ratio between two polynomials in the scale factor of the universe. Using the latest cosmological data we perform a standard likelihood analysis...
