Tension and constraints on modified gravity parametrizations of from growth rate and Planck data
Savvas Nesseris, George Pantazis, Leandros Perivolaropoulos
We construct an updated and extended compilation of growth rate data consisting of 34 points and including corrections for model dependence. In order to maximize the independence o…

A Comparison of Thawing and Freezing Dark Energy Parametrizations
G. Pantazis, S. Nesseris, L. Perivolaropoulos
Dark energy equation of state parametrizations with two parameters and given monotonicity are generically either convex or concave functions. This makes them suitable for fi…
