S_8 ≡ σ_8 √(Ω_m / 0.3) = 0.815^{+0.016}_{-0.021}, found to be in agreement (0.73σ) with results from the Planck Legacy cosmic microwave background experiment.
The new physically motivated intrinsic alignment model that depends jointly on halo mass and spectral type distributions, together with the improved redshift distribution estimation extending to z_B ≤ 2.0, accurately captures all relevant systematics.
KiDS-Legacy measures S8 = 0.815^{+0.016}_{-0.021} from cosmic shear over 1347 square degrees, consistent with Planck at 0.73 sigma.
