Joint (f,σ8) constraints at different redshifts. The combined RSD and galaxy-galaxy lensing posterior likelihood contours at 1σ and 2σ and those from Gil-Marín et al. (2017), obtained by combining redshift-space power spectrum and bispectrum information in the BOSS survey, are presented. The solid curve and associated grey shaded area correspond to the expectations and 68% uncertainty for General Relativity in a ΛCDM background model set to TT+lowP+lensing Planck 2015 predictions (Planck Collaboration XIII 2016), as a function of redshift from z = 2 to z = 0.
