Physics of Gamma-Ray Bursts: Turbulence, Energy Transfer and Reconnection

Understanding of the nature of gamma-ray bursts (GRBs) is one of the challenging problem facing the astrophysics community. The field of gamma ray bursts is a rapidly developing one and we expect that new missions, like SWIFT and GLAST will bring the field to a new quantitative level. The detail of the explosion, the formation of the fireball, its propagation, the generation of the shocks, the source of the magnetic fields and soft photons, the particle acceleration process, and the details of the radiation process are all still outstanding questions. The goal of this review is to attract the attention of the community to a number of physical processes (MHD turbulence and particle acceleration, magnetic reconnection, etc.) that seem to be very relevant for these sources.
