Dependency of the SN-driven small-scale dynamo mechanism on the percentage of kinetic energy that goes into turbulence β and the SN efficiency α. The upper panel shows the different length scales, the middle panel the time until saturation, i.e. t_ν and t_L, and the lower panel the saturation magnetic field strength B_sat. We plot all quantities on the viscous scale ℓ_ν and on the turbulent forcing scale L as indicated in the figure. The dashed-dotted blue line represents the case of a spherical galaxy with α = 0.001, the solid blue line the fiducial case of α = 0.01 and the dotted blue line the case of α = 0.1. The dashed red line shows the results for a disk-like galaxy. There are only 6 lines in the lower plot instead of 8. This results from the fact, that in the spherical case the saturation field strength on the forcing scale does not depend on α nor on β, in contrast to L and t_L (see Eqs. (80) to (84)).
