Beschreibung

The Oxford Atomic and Laser Physics webinar series welcomes Petros Tzeferacos (Rochester)

I present an overview of the exciting fundamental science in magnetized astrophysical plasmas that the TDYNO team is accomplishing through concerted application of the FLASH code and laboratory plasma astrophysics experiments. Our international collaboration, co-lead by the University of Oxford and the Flash Center for Computational Science, has conducted recent breakthrough experiments in the study of turbulent dynamo. This ubiquitous astrophysical mechanism is thought to be responsible for present-day magnetization of numerous celestial objects but had eluded laboratory plasma physicists for decades. The experiments have enabled us to explore dynamo in various regimes, providing us with novel insights and a new tool to validate or falsify our theoretical understanding. I will also describe how these experiments are enabling laboratory investigations of cosmic ray (CR) acceleration, the diffusive transport of extragalactic and ultra-high energy CRs, and the strong suppression of heat conduction in galaxy clusters.
