![]() At cosmological scales, the advent of wide field survey experiments currently yields very high precision measurements in both the early and late ages of the universe. Since its inception, general relativity theory (GR) has been constantly tested, starting with observations in the solar system and in our Galaxy (see e.g. Open Access article, published by EDP Sciences, under the terms of the Creative Commons Attribution License ( ), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. We make our mock catalogues available on the Skies and Universe database. This analysis reveals that RSD efficiently decreases the GGL uncertainty on Ω m by a factor of 4 and by 30% on σ 8. We also estimate the probe of gravity E G = 0.43 ± 0.10, in agreement with ΛCDM−GR predictions of E G = 0.40. Together with additional spectroscopic data, this helps us to quantify and correct several systematic errors, such as photometric redshifts. We used an N-body simulation supplemented by an abundance matching prescription for CMASS galaxies to build a set of overlapping lensing and clustering mocks. We adjusted a model that includes non-linear biasing, RSD, and Alcock–Paczynski effects. deg using shape catalogues from CFHTLenS and CFHT-Stripe 82 and spectroscopic redshifts from the BOSS CMASS sample. We performed a joint GGL and RSD analysis on 250 sq. The combination of galaxy-galaxy lensing (GGL) and redshift space distortion of galaxy clustering (RSD) is a privileged technique to test general relativity predictions and break degeneracies between the growth rate of structure parameter f and the amplitude of the linear power spectrum σ 8.
