Understand

The effective anisotropic stress or gravitational slip $\eta=-\Phi/\Psi$ is a key variable in the characterisation of the physical origin of the dark energy, as it allows to test for a non-minimal coupling of the dark sector to gravity in the Jordan frame.

It is however important to use a fully model-independent approach when measuring $\eta$ to avoid introducing a theoretical bias into the results.
In this paper we forecast the precision with which future large surveys can determine $\eta$ in a way that only relies on directly observable quantities.
In particular, we do not assume anything concerning the initial spectrum of perturbations, nor on its evolution outside the observed redshift range, nor on the galaxy bias.
