Measuring growth index in a Universe with sterile neutrinos
Consistency tests for the general relativity (GR) can be performed by constraining the growth index γ using the measurements of redshift-space distortions (RSD) in conjunction with other observations. In previous studies, deviations from the GR expected value of γ≈0.55 at the 2–3σ level were found....
