Numerical Studies of Particles and Fluids in Astrophysics

The Jones group maintains a unique and highly successful study of the acceleration and propagation of high-energy charged particles in cosmic plasmas (so-called "cosmic rays”), and their contributions to frontier astrophysical problems. The group’s codes, all developed in-house, combine high performance, multidimensional magnetohydrodynamics (MHD) with highly efficient treatments of diffusive transport of cosmic rays. The researchers have recently rewritten their basic MHD code to improve its performance and to scale to thousands of processors, enabling them to tackle some fundamental and challenging astrophysical problems of a scale they have not been able to do previously at MSI. They also have now incorporated their unique cosmic ray transport scheme into a new adaptive mesh refinement multidimensional MHD code developed jointly with collaborators at the University of Rochester. This also opens the door to a new class of astrophysical problem. This is the only group anywhere attempting these simulations.
