Plot of fσ₈ vs. redshift, showing the VIPERS results together with a compilation of recent measurements. The previous results from the VVDS (Guzzo et al. 2008), SDSS-MGS (Howlett et al. 2015), SDSS-LRG (Samushia et al. 2012), WiggleZ (Blake et al. 2012), BOSS (Reid et al. 2012), 6dFGS (Beutler et al. 2012), and FastSound (Okumura et al. 2016) surveys are shown with the different symbols (see inset). The solid curve and associated error correspond to the prediction for general relativity in a ΛCDM model set to Planck 2015 cosmological parameters (Planck Collaboration XIII 2016).
