Prof. Bing Zhang received a near $400,000 research grant from NASA's Astrophysics Theory Program. The grant is to support his research group in developing novel theoretical models of relativistic astrophysical jets in the magnetically dominated regime. The models will use a relativistic magnetohydrodynamic (MHD) code and conduct global and local simulations of colliding magnetically dominated shells. They also will investigate the detailed physical processes of collision-triggered magnetic reconnection and dissipation, particle acceleration and radiation, as well as the light curves, spectra, and polarization properties of the emission. The results from the proposal will be applied to understand the physical mechanisms of gamma-ray bursts and other relativistic jets in the universe.
