    • The effect of finite halo size on the clustering of neutral hydrogen. 

      Umeh, O; Maartens, R; Camera, S (IOP, 2021)
      Post-reionisation 21cm intensity mapping experiments target the spectral line of neutral hydrogen (HI) resident in dark matter haloes. According to the halo model, these discrete haloes trace the continuous dark matter ...

    • Interacting dark energy from redshift-space galaxy clustering 

      Carrilho, P; Moretti, C; Bose, B; Pourtsidou, A (IOP Publishing, 2021)
      Interacting dark energy models have been proposed as attractive alternatives to CDM. Forthcoming Stage-IV galaxy clustering surveys will constrain these models, but they require accurate modelling of the galaxy power ...

    • Probing beyond-Horndeski gravity on ultra-large scales 

      Moloi, Teboho; Duniya, Didam; Clarkson, Chris (2020)
      The beyond-Horndeski gravity has recently been reformulated in the dark energy paradigm — which has been dubbed, Unified Dark Energy (UDE). The evolution equations for the given UDE appear to correspond to a non-conservative ...
