A multi-scale view of molecular gas and magnetic fields in the Antennae galaxies

Akhil Lasrado, Enrique Lopez-Rodriguez, Claudia Cicone +5

Major mergers are transformative events in galaxy evolution, dynamically reshaping the stellar and gas makeup of the hosts, as well as the galaxy-scale magnetic fields (B-fields) t…

Fast, Stable, and Physical: Hyperbolic, Magnetic Field-Aligned Diffusion in SPH

Nicholas Owens, James Wadsley, Robert Wissing +1

In this paper, we introduce the first implementation of magnetic field-aligned hyperbolic diffusion for standard smoothed particle (magneto-)hydrodynamics (SPH), and its linear-exa…
