This 1-day long Chicagoland-based DES meeting creates a common discussion platform for those who work on Dark Energy Survey (DES) at the KICP, University of Chicago, Fermilab, UIUC, NCSA, and Argonne. The ongoing Dark Energy Survey is designed to probe the origin of the accelerating universe and help uncover the nature of dark energy by measuring the 14-billion-year history of cosmic expansion with high precision. Learn more about the survey at the DES website. The objectives of this meeting are to provide updates and to discuss various science/infrastructure projects that are going on in Chicagoland and to provide a channel for interested people to join ongoing and create new projects.
