The Dark Energy Survey (DES) is a stage-III photometric galaxy survey designed to constrain the properties of dark energy from four main probes. The survey was carried out for six years, finishing in 2019. As a result, it has provided a rich dataset to explore the large-scale structure of the Universe through the effect of weak gravitational lensing and galaxy clustering.
In this talk, We will present our legacy cosmological results from the combination of weak lensing and galaxy clustering using the full six years of observations (Year 6).
