NCSA, CAPS Energy Dark Energy Survey’s Most Complete Growth Historical past Evaluation | NCSA | National Center for Supercomputing Applications | Workplace of the Vice Chancellor of Analysis and Innovation

The Dark Energy Survey (DES) not too long ago revealed results that mix all six years of knowledge collected from weak lensing and galaxy clustering probes – a primary for the worldwide collaboration that’s mapping tons of of hundreds of thousands of galaxies, detecting 1000’s of supernovae and analyzing patterns of cosmic construction that would reveal what’s accelerating the growth of the universe.

The Center for AstroPhysical Surveys (CAPS) led end-to-end information processing and archival for DES utilizing the DES Data Management System on the National Center for Supercomputing Applications. NCSA operated the information administration and computing infrastructure that processed, quality-controlled and served the total DES imaging and catalog information set, enabling the creation of science-ready sky maps and cosmological measurements.

“Dark energy and the universe’s accelerating expansion sit at the boundary between what we can measure precisely and what we can explain,” mentioned CAPS Director Joaquin Vieira. “Pinning down what’s driving that acceleration would reshape our understanding of the universe’s destiny and power revisions to the deepest legal guidelines that describe area, time and matter.

“The latest results from the Dark Energy Survey were enabled by CAPS leadership and NCSA’s data management and computing backbone.”

This new evaluation from DES narrows the controls in modeling the conduct of the universe because of combining the information from 4 totally different probes: baryon acoustic oscillations, type-Ia supernovae, galaxy clusters and weak gravitational lensing. Scientists hope to make use of this analysis to discover varied different fashions for phenomena within the universe, together with darkish vitality and different gravity.

“The latest DES release emphasizes that the new constraints are tighter than prior DES analyses while remaining broadly consistent with earlier DES results,” Vieira mentioned. “It frames the methodology as a template for next-generation surveys such as the U.S. National Science Foundation and Department of Energy’s Vera C. Rubin Observatory Legacy Survey of Space and Time.”

CAPS connects information infrastructure experience at NCSA to astrophysics groups on the University of Illinois Urbana-Champaign and helps the individuals and workflows that flip survey-scale information into science outcomes. NCSA is a founding companion of the DES venture, together with Fermilab and NOIRLab.
