    • Evidence for cosmic acceleration with next-generation surveys: A model-independent approach 

      Bengaly, Carlos A. P. (Oxford University Press, 2020)
      We 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 kinematic dipole in galaxy redshift surveys 

      Maartens, Roy; Clarkson, Chris; Chen, Song (IOP Publishing, 2018)
      In the concordance model of the Universe, the matter distribution { as observed in galaxy number counts or the intensity of line emission (such as the 21cm line of neutral hydrogen) - should have a kinematic dipole due ...
