I worked with lead author Raphael Skalidis, Aris Tritsis, and Philip F. Hopkins.</p> <p>Using simulations of weakly compressible turbulence with a strong mean magnetic field, we compare driving through velocity fluctuations with driving through magnetic fluctuations. The two methods produce different energy balances even at comparable sonic and Alfvénic Mach numbers.</p> <p>Magnetic driving produces nearly equal kinetic and magnetic energies in the inertial range, while velocity driving leaves an excess of kinetic energy. Section 3 of the <a href="https://arxiv.org/html/2512.11973v2">paper</a> presents the numerical comparison, showing why the driving mechanism matters when interpreting magnetized turbulence.</p> <p><a href="https://doi.org/10.1051/0004-6361/202558554">Read the published paper</a> or <a href="https://arxiv.org/abs/2512.11973">read the open preprint</a>.</p>
