This shows the HACC cosmology simulation, which combines high spatial and temporal resolution in a large cosmological volume. The high temporal resolution tracks the evolution of structures in great detail and correlates formation histories to the environments in which the structures form.

Cartography of the cosmos

There are hundreds of billions of stars in our own Milky Way galaxy, interspersed with all manner of matter, from the dark to the sublime. This is the universe that Argonne researcher Salman Habib is trying to reconstruct, structure by structure, combining telescope surveys with next-generation data analysis and simulation techniques currently being primed for exascale computing.
