Joint-probe comparison of S₈ and Ω_m constraints. Our fiducial results (KiDS 2 × 2 pt +SMF) can be compared to: a similar 2 × 2 pt +SMF analysis from the SDSS (Cacciato et al. 2013); a series of 2 × 2 pt studies that includes the latest results from DES (Porredon et al. 2022; Pandey et al. 2022) and the HSC survey (Miyatake et al. 2022b); and 3 × 2 pt analyses from KiDS with BOSS (Heymans et al. 2021) and DES (DES Collaboration 2022). The last entry shows the Planck Collaboration VI (2020, TT,TE,EE+lowE) constraints. Our results are consistent with all studies, including Planck Collaboration VI (2020), although we find a mild tension between our S₈ constraints and those from Planck, at the level of 1.9σ.
