The cascade of kinetic and magnetic energy from large to small scales in galactic-style turbulence behaves significantly different to the theoretical models that we regularly assume work.

Last week we submitted a study to ApJL confronting the predictions from weakly compressible MHD theory with extremely high Re simulations and in situ measurements of Earth’s high beta magnetosheath, showing agreement between theory, simulation and observations. arxiv.org/abs/2502.08883

FB sent me this memory from 8 years ago — the last time I was an experimentalist working on a stellerator confinement machine at the ANU.

One of my favorite plots for the year. The spatial distribution of the energy flux in a supernova-driven galactic disk. Red means inverse turbulence cascade, from small to large scales, blue means direct turbulence cascade, from large to small scales. The turbulence goes both ways! Mind-blowing!
