Top: a snapshot of the ﹩{ \mathcal M }=8﹩ simulation at t_peak illustrating the complex structures that form in supersonically turbulent simulations. The image is colored on a ﹩\mathrm{log}﹩scale in which regions that are more dense than m_in₀ are blue, less dense regions are red, and values about ρ = m_in₀ = 1 are black. Yellow lines show magnetic field lines, and white arrows indicate the direction and relative magnitude of bulk flows. A white horizontal line is drawn at Y = 200d_i to show where the cuts plotted in the panel below are taken, and faint white vertical lines are guides to aid in comparing the top and bottom panels. Bottom: plots of ﹩\mathrm{log}\rho ﹩ (blue; left axis) and B_y (yellow; right axis) as a function of X, where Y = 200d_i. A dotted black line indicates a value of 0 for both quantities.
