Characteristic amplitude of δρ/ρ, , for the models with weak turbulence M ~ 0.25 and varying conduction, after reaching statistical steady state (~2 t_eddy) with the same level of continuous stirring. The driving is initiated only above 550 kpc. From top to bottom curve (black to bright red), the suppression of conduction is f = 0,   10^-3,   10^-2,   10^-1,   1. First column of Table 1 summarizes the key properties. Strong conduction globally damps δ perturbations by a factor of 2−4, substantially steepening the spectrum and departing from the Kolmogorov slope of the no-conduction run. Weak conduction is able to induce the steep decay only near the scale linked to P_t ~ 100.
