Parametric and nonparametric methods hint dark energy evolution
Reginald Christian Bernardo, Daniela Grandón, Jackson Levi Said +1
We study dark energy through the viewpoints of parametric and nonparametric analyses of late-time cosmological data. We consider four Hubble parameter priors reflecting the Hubble…
Cosmic slowing down of acceleration for several dark energy parametrizations
Juan Magaña, Víctor H. Cárdenas, V. Motta
We further investigate slowing down of acceleration of the universe scenario for five parametrizations of the equation of state of dark energy using four sets of supernovae data. I…
Semi-holographic model revisited
Víctor H. Cárdenas, J. R. Villanueva, Juan Magaña
In a recent work Zhang, Li and Noh [Phys. Lett. B {\bf 694}, 177 (2010)]proposed a model for dark energy assuming this component strictly obeys the holographic principle. They perf…
