Null tests of the concordance model in the era of Euclid and the SKA
  We perform null tests of the concordance model, using $H(z)$ measurements
that mimic next-generation surveys such as Euclid and the SKA. To this end, we
deploy a non-parametric method, so that we make minimal assumptions about the
fiducial cosmology as well as the statistical analysis. We produce simulations
assuming different cosmological models in order to verify how well we can
distinguish between their signatures. We find that SKA- and Euclid-like surveys
should be able to discriminate sharply between the concordance and alternative
dark energy models that are compatible with the Planck CMB data. We conclude
that SKA and Euclid will be able to falsify the concordance model in a
statistically significant way, if one of the benchmarks models represents the
true Universe, without making assumptions about the underlying cosmology.
