Recent cosmology results and modeling challenges from Year 3 data of the Dark Energy Survey

Abstract: I will give an overview of the cosmology analysis of weak lensing and clustering measurements from Year 3 data from the Dark Energy Survey. This analysis is detailed in 30 papers, available at https://www.darkenergysurvey.org/des-year-3-cosmology-results-papers/; I will focus here on the theoretical modeling of the mean signal and covariance, as well as metrics for assessing the agreement or tension between different measurements. I will summarize the cosmological results, and highlight outstanding modeling challenges, especially the clustering anomaly X_lens.
