Scale-bridging plasma dynamics to understand relativistic astrophysical jets (F07#)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 445052434

The objective is to design a simulation tool that cleverly combines fluid and kinetic algorithms in such a way that the full physics of reconnection processes can be covered with as little computational effort as possible. The tool will be built in three steps: Hamiltonian formulation and closure of the fluid moment equations, extension of geometric particle-in-cell methods to the relativistic case for the description of kinetic effects and a structure-preserving bulk coupling of the two. Ba-sed on the developed research code we will study the physics of the plasmoid instability to under-stand astrophysical jets.
