Residual energy in magnetized turbulence, published in A&A
Our paper, Residual energy in weakly compressible turbulence with a mean guide field, is published in Astronomy & Astrophysics, 713, A7. I worked with lead author Raphael Skalidis, Aris Tritsis, and Philip F. Hopkins.
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.
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 paper presents the numerical comparison, showing why the driving mechanism matters when interpreting magnetized turbulence.
