In this video from ATPESC 2019, Katrin Heitmann from Argonne National Laboratory presents: Exploring the Dark Universe.

Next-generation observatories will open new routes to understand the true nature of the ‘Dark Universe’. These observations will pose tremendous challenges on many fronts — from the sheer size of the data that will be collected (more than a hundred Petabytes) to its modeling and interpretation. The interpretation of the data requires sophisticated simulations on the world’s largest supercomputers. The cost of these simulations, the uncertainties in our modeling abilities, and the fact that we have only one Universe that we can observe opposed to carrying out controlled experiments, all come together to create a major test for computational, statistical, and data analysis methods.

Katrin Heitmann is a Physicist and Computational Scientist at Argonne National Laboratory in the High Energy Physics Division. She is also a Senior Member of the Kavli Institute for Cosmological Physics at the University of Chicago and a member of NAISE at Northwestern. Before joining Argonne, Katrin was a staff member at Los Alamos National Laboratory. Her research currently focuses on computational cosmology, in particular on trying to understand the causes for the accelerated expansion of the Universe. She is responsible for large simulation campaigns with HACCand for the tools in the associated analysis library, CosmoTools. Katrin is a member of several major astrophysical surveys that aim to shed light on this question and is the currently the Computing Coordinator for the Large Synoptic Survey Telescope Dark Energy Science Collaboration.
