Universe

The accelerated expansion of the Universe is the most surprising cosmological discovery in decades. It has inspired a new generation ambitious surveys to determine the fundamental nature of this acceleration. I will introduce the different measurement techniques used by these surveys, and describe the landscape of current and near future cosmological sky surveys, highlighting early results from the ongoing Dark Energy Survey (DES) and the ongoing joint analysis of DES and South Pole telescope data. The unprecedented data quality and data volume of future surveys will require a new generation of analysis frameworks, and I will conclude by outlining some of the statistical and computational challenges for the interpretation of these data sets.
