  • When Stars Collide: 3D Computer Simulation Captures Cosmic EventExternal link

    01.17.19 The aftermath of the collision of two neutron stars has been fully captured in a 3D computer model for the first time, thanks to research by University of Alberta astrophysicist Rodrigo Fernández and an international team. The achievement, which used supercomputing resources at Lawrence Berkeley National Laboratory’s National Energy Research Scientific Computing Center, has led to a better understanding of the cosmic collision, showing how heavy elements like lead and gold are created and accounting for a phenomenon missing in other models.

  • Fiery Sighting: A New Physics of Eruptions That Damage Fusion ExperimentsExternal link

    01.17.19 Sudden bursts of heat that can damage the inner walls of tokamak fusion experiments are a hurdle that operators of the facilities must overcome. Such bursts, called “edge localized modes (ELMs),” occur in doughnut-shaped tokamak devices that house the hot, charged plasma that is used to replicate on Earth the power that drives the sun and other stars. Now researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have directly observed a possible and previously unknown process that can trigger damaging ELMs.
