Fluid and Magnetofluid Modeling of Relativistic Magnetic Reconnection

The fluid-scale evolution of relativistic magnetic reconnection is investigated by using two-fluid and magnetofluid simulation models. Relativistic two-fluid simulations demonstrate the meso-scale evolution beyond the kinetic scales, and exhibit quasi-steady Petschek-type reconnection. Resistive relativistic MHD simulations further show new shock structures in and around the downstream magnetic island (plasmoid). General discussions on these models are presented.
