AREPO-RT: Radiation hydrodynamics on a moving mesh
Rahul Kannan, Mark Vogelsberger, Federico Marinacci +3
We introduce AREPO-RT, a novel radiation hydrodynamic (RHD) solver for the unstructured moving-mesh code AREPO. Our method solves the moment-based radiative transfer equations usin…
Non-ideal magnetohydrodynamics on a moving mesh
Federico Marinacci, Mark Vogelsberger, Rahul Kannan +3
In certain astrophysical systems the commonly employed ideal magnetohydrodynamics (MHD) approximation breaks down. Here, we introduce novel explicit and implicit numerical schemes…
A moving mesh unstaggered constrained transport scheme for magnetohydrodynamics
Philip Mocz, Ruediger Pakmor, Volker Springel +3
We present a constrained transport (CT) algorithm for solving the 3D ideal magnetohydrodynamic (MHD) equations on a moving mesh, which maintains the divergence-free condition on th…
