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,…

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…
