Radial profile of the velocity (top), the shear parameter (middle) and the Mach number (bottom) for the N_J = 8 and N_J = 16 no-feedback runs and for the SB and BW feedback runs with N_J = 8 (light color t = 250 Myr, dark color 2 Gyr). The turbulent velocities are enhanced by the gravitational instability of the disk and the inclusion of feedback. However, BW can be seen to produce a lower turbulent response compared to SB, especially at later times (within 10 kpc). In all runs we can see that there is a reduction of the shearing parameter toward the central region, reducing the effectiveness of an αΩ type dynamo. Mach numbers are lower in the BW model due to the heating of the disk and the relatively low turbulent velocities.
