B3P2f-art123s1-file2_1600x900web (IMAGE) DOE/Argonne National Laboratory Caption This visualization provides a first look at data from a science demonstration run carried out on Aurora. It shows baryons overlaid on the internal energy (proportional to the gas temperature) from a HACC simulation. The simulation evolved 200 billion dark matter and baryonic tracer particles in a (1512 Mpc/h)³ volume with the CRK-HACC framework.
