Cosmological insights from three years of DES

Thursday 07/10/2021 @ 11:30, Remote talk
The Dark Energy Survey has recently presented cosmological results from weak lensing and galaxy clustering two-point functions using data collected in the first three years of operations. The combination of area (>4000 deg^2) and depth (100 million lensing source galaxies observed) significantly exceeds the previous state of the art, requiring the development of new methodology in several areas of cosmological data analysis. Here I review the results from this effort and give an outlook on what needs to be done such that future, even more powerful, data sets can be fully utilized.
