Evolution of stellar (first and second rows) and dust emission maps (third and fourth rows) of the Milky Way-like galaxy simulation. The panels show the emission maps at t = 0.05, 0.5, 1, 3, and 10 Gyr from left to right. The images on the first and third (second and fourth) rows are face-on (edge-on) views. The stellar emission maps consist of the SDSS i (red), r (green), and 𝑔 (blue) fluxes with an additionally enhanced blue level for the GALEX FUV flux. The dust emission maps are synthesized by the Spitɀer IRAC 8 μm (blue), Herschel PACS 70 μm (green), and Herschel PACS 160 μm (red) fluxes.
