Supercomputer Unveils Secrets of Dark Matter

Researchers from the University of California, Santa Cruz, have used the Oak Ridge Leadership Computing Facility's Summit supercomputer to run extensive simulations investigating the properties of dark matter. By modeling the Lyman-Alpha Forest, a series of absorption features formed by distant quasars, the team compared the results with observations and found that warm dark matter, with faster thermal velocities, may be a more accurate description of the universe's dark matter than the commonly accepted cold dark matter model. The study also highlights the computational feat achieved by the team, using state-of-the-art simulation software and the power of the world's largest supercomputers.
