KiDS-Legacy: Cosmological constraints from cosmic shear with the complete Kilo-Degree Survey

Angus H. Wright, Benjamin Stölzner, Marika Asgari, Maciej Bilicki et al.

Short summary

The completed Kilo-Degree Survey (KiDS) yields a cosmological parameter S 8 = 0.81 +0.016 −0.021, in 0.73σ agreement with Planck, and a ~32% improvement in constraining power for Σ 8 = 0.821 +0.014 −0.016 using an extended sample to z=2.0.
