Understand

In this work, we use recent data on the Hubble expansion rate $H(z)$, the quantity $f\sigma_8(z)$ from redshift space distortions and the statistic $E_g$ from clustering and lensing observables to constrain in a model-independent way the linear anisotropic stress parameter $\eta$.

This estimate is free of assumptions about initial conditions, bias, the abundance of dark matter and the background expansion.
We denote this observable estimator as $\eta_{{\rm obs}}$.
If $\eta_{{\rm obs}}$ turns out to be different from unity, it would imply either a modification of gravity or a non-perfect fluid form of dark energy clustering at sub-horizon scales.
