Morphology of the MC at the reference snapshot, zooming on the central region of the box with a side length of 20 pc. The maps refer to the reference observing direction. Top panels show the dust surface density (left panel), the photon density-weighted Habing flux G₀ (middle panel) and the photon density-weighted ionizing flux U_ion (right panel). Blue circles in the top left panel mark the position of stellar particles. The bottom panels show the UV emission (left panel), IR emission (middle panel), and V -band optical depth (right panel), computed from the post-processing RT. The maps in the bottom row are smoothed with a Gaussian kernel of σ = 1 pixel with respect to the original resolution. For the same diagnostics at different evolutionary times, see Figs. A.1, A.2, and A.3.
