Numerical Studies of Particles and Fluids in Astrophysics

These researchers are continuing their unique and highly successful study of the dynamics of diffuse, conducting media in astrophysical environments and their roles in mediating the acceleration and propagation of high-energy charged particles (so-called “cosmic rays”). The group’s codes, all developed by this group and their collaborators, combine high performance, highly scalable, multidimensional magnetohydrodynamics (MHD) algorithms with uniquely efficient treatments of diffusive transport of cosmic rays. These tools allow the researchers to address a wide range of critical and fundamental astrophysical problems. Their program centers around large simulations on MSI’s supercomputers. Each of these projects provides the base material for a student Ph.D. thesis.
