      Ambiguous tests of general relativity on cosmological scales 

      Zuntz, J.; Baker, T.; Ferreira, P. G.; Skordis, C. (2012)
      There are a number of approaches to testing General Relativity (GR) on linear scales using parameterized frameworks for modifying cosmological perturbation theory. It is sometimes assumed that the details of any given ...

      The Parametrized Post-Newtonian-Vainshteinian formalism 

      Avilez-Lopez, A.; Padilla, A.; Saffin, P. M.; Skordis, C. (2015)
      Light degrees of freedom that modify gravity on cosmological scales must be ''screened on solar system scales in order to be compatible with data. The Vainshtein mechanism achieves this through a breakdown of classical ...
