Monthly Notices of the Royal Astronomical Society: Letters, Volume 499(1),L6–L101365-2966https://doi.org/10.1093/mnrasl/slaa040http://hdl.handle.net/10566/5899We quantify the evidence for cosmic acceleration using simulations of H(z) measurements from SKA- and Euclid-like surveys. We perform a non-parametric reconstruction of the Hubble parameters and its derivative to obtain the deceleration parameter q(z) using the Gaussian Processes method. This is a completely model-independent approach, so we can determine whether the Universe is undergoing accelerated expansion regardless of any assumption of a dark energy model.enObservationsCosmologyCosmic accelerationDark energy modelGalaxy redshiftArticle
