Smoothed particle magnetohydrodynamics for simulations of galaxy and cosmic structure formation
Orestis A. Karapiperis, Matthieu Schaller, Nikyta Shchutskyi +2
We introduce a novel formulation of cosmological smoothed particle magnetohydrodynamics (SPMHD), designed to model magnetic field physics in a vast array of nonlinear astrophysical…

Kinematic dynamos and resolution limits for Smoothed Particle Magnetohydrodynamics
Nikyta Shchutskyi, Matthieu Schaller, Orestis A. Karapiperis +2
Understanding the origin and evolution of magnetic fields on cosmological scales opens up a window into the physics of the early Universe. Numerical simulations of such fields requ…

Numerical tests of cosmological Alfvén waves with Ohmic diffusion
Orestis A. Karapiperis, Matthieu Schaller
Physical problems with a solution that can be expressed analytically are scarce; this holds even more true for problems set in a cosmological context. Such solutions are, however,…
