Origin of Milky Way’s Hypothetical Dark Matter Signal May Not Be So Dark
Galaxy’s excessive gamma-ray glow likely comes from pulsars, the remains of collapsed ancient stars according to a new analysis by an international team of astrophysicists, including researchers from the Department of Energy’s SLAC National Accelerator Laboratory.

Nuclear fusion has long promised to provide a safe and clean source of virtually limitless energy. Developing efficient devices that fulfill that potential, sustainably, demands a scientific and engineering effort that is a major area of plasma physics research today. Researchers at the Argonne Leadership Computing Facility (ALCF), a U.S. Department of Energy Office of Science User Facility, have helped to accelerate this effort by making available near-real-time data analysis to the experiments conducted to design such devices.
