Global simulations of heat-flux-driven buoyancy and magnetothermal instabilities, and their astrophysical implications

In this thesis, we investigate the convective instabilities induced by anisotropic conduction in a rapidly conducting plasma. We simulate the magneto-thermal instability (MTI), and the heat-flux-driven buoyancy instability (HBI) in two- and three- dimensional, global hydrodynamic simulations performed by the AREPO code, and verify the results of previous works. Our results have important astrophysical implications, such as the conductive heat transport in galaxy clusters.
