State-of-the-art computing resources located at NERSC are aiding in the long and complicated process of understanding data from the Planck spacecraft that is attempting to illuminate the nature and origin of dark matter in the universe.

Scientists are creating high-resolution maps of extremely subtle variations in temperature and polarization of the Cosmic Microwave Background (CMB), which is leftover light from the Big Bang that permeates the universe. The work relies on a team of NERSC experts that knows how to optimize and maintain well-balanced high performance computing systems as well as supercomputers with sufficient I/O (input/output) capability.

QCD

Validating Fundamental Forces of Nature

William & Mary Professor of Physics William Detmold and his colleagues have achieved the first quantum chromodynamics (QCD) calculations of the three-body force between hadrons. A better understanding of these interactions could ultimately improve models of nuclei, as well as provide valuable insights into the life and death of stars.
