Figure 4: Nonlocal transport parameter (a, c) and Mach Numbers (b, d) for simulations at various values of mass ratio and cooing parameter , where varies, and where varies, . For the Mach number plots, heavy lines denote the Mach number as measured in an inertial (static) frame, whereas light lines show the Doppler-shifted Mach number (measured in a frame corotating with the fluid).
