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…

In-situ vs. ex-situ drivers of galaxy quenching: critical black hole mass and main sequence universality in the FLAMINGO simulation
Seunghwan Lim, Sandro Tacchella, Roberto Maiolino +2
Exploiting a large sample of 5.3 million galaxies with from the highest-resolution FLAMINGO simulation, we carry out a statistical analysis…
