Snapshots of the TVD runs with (a) ﹩M_{s}=1﹩ at ﹩t=5\tau _{\mathrm{turb}\,}﹩ and (b) ﹩M_{s}=6﹩ at ﹩t=4.5\tau _{\mathrm{turb}\,}﹩. Note how the turbulent fragmentation of the medium is different for different Mach numbers. Blue, green, yellow, orange, and red colors represent isodensity surfaces with 1, 2, 3, 4, and 5 times the mean density in (a). In (b), the same order of colors represents isodensity surfaces with 5, 11.25, 17.5, 23.75, and 30 times the mean value.
