Researchers are leveraging powerful supercomputers to investigate one of the key observational probes of "dark energy." The project focuses on simulations created on Ohio Supercomputer Center systems to simplify and better characterize a subtle dark-matter clustering feature. The new model allows cosmologists to gain a more accurate understanding of certain aspects of large-scale structure, such as the effect of the expansion of the universe on the growth of density fluctuations.
