Adapting AREPO-RT for Exascale Computing: GPU Acceleration and Efficient Communication
Oliver Zier, Rahul Kannan, Aaron Smith +2
Radiative transfer (RT) is a crucial ingredient for self-consistent modelling of numerous astrophysical phenomena across cosmic history. However, on-the-fly integration into radiat…
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…
