Face-on (top) and edge-on (bottom) projection of the simulated galaxy at t = 0. We mark the explosion sites of the SNRs with star markers. Different marker colors correspond to the different passive scalars associated with the SN ejecta. The ISM in the inner ∼10 kpc is highly structured with filamentary outflows that reach several kpc above the midplane, while the ISM in the outskirts is rather smooth without any prominent vertical features.
