Prof. Zhang receives a NASA Fermi grant.

Aug 28, 2010

Prof. Zhang received an award from the Fermi Gamma-ray Space Telescope Cycle 3 with a total amount of $80,000. The title of his theoretical proposal is “A New Model of GRB Prompt Emission”. Zhang and collaborators propose to develop of new model of GRBs in the Poynting-flux-dominated regime, namely, the Internal Collision-induced Magnetic Reconnection and Turbulence (ICMART) model.

They plan to work on the following three directions: (1) an analytical study of particle acceleration and radiation in an ICMART event; (2) a numerical MHD simulation of collisions of two high-sigma shells to observe developement of turbulence; (3) a multiple-shell numerical model for collisions of high-sigma shells. The results will be applied to directly model GRB 080916C and other Fermi GRBs.
