The Micro?Macro Coupling of Mass?Loading in Symmetric Magnetic Reconnection With Cold Ions

We investigate how magnetic reconnection is influenced by an inflow of a dense cold ion population. compare two 2.5D Particle-In-Cell simulations, one containing the population and without. find that influences process on both global kinetic scales, dominant contribution can be explained through mass-loading. provide analysis these multiscale changes are related processes in diffusion region, so-called micro-macro coupling The inertia found to significant link connects different scales. warm populations exhibit counter streaming behavior when after region reorganizes itself response arrival This signature should observable spacecraft observatories such as MMS.
