Evolution of 1, 0.1, 0.01, and 0.001 micron radius dust grains (from left to right) under sputtering in a multi-phase galactic outflow. The galaxy has a star formation rate of 20 solar masses per year, with clusters distribuetd throughout the disk at a scale radius of 800 pc.

Evolution of 1, 0.1, 0.01, and 0.001 micron radius dust grains (from left to right) under sputtering in a multi-phase galactic outflow. The galaxy has a star formation rate of 5 solar masses per year and centrally concentrated star clusters, distrbuted at a scale radius of 300 pc in the disk.

The mixed-phase cooling time is much longer than the shear time.

The mixed-phase cooling time is short compared to the shear time.
