Description

The Kilo-Degree Survey (KiDS) provides some of the most precise measurements of weak gravitational lensing, enabling stringent constraints on the cosmological model from wide-field imaging data. In this talk, I will discuss the key methodological developments with respect to earlier KiDS analyses, and present the latest cosmological constraints from the fifth and final KiDS data release. I will then discuss the updated KiDS-Legacy results in light of the apparent $S_8$ tension between probes of the early and late Universe. Additionally, I will review tests of the internal consistency of the KiDS-Legacy dataset and summarize results from follow-up projects exploring extensions to the standard cosmological model. Finally, I will give an outlook on upcoming analyses of cosmic shear combined with galaxy clustering and galaxy-galaxy lensing with KiDS.
