Cuts along the y-axis at radii of 2.5 and 5.0 kpc (dashed red and cyan lines) for comparison between the observations and the simulation. The left panel represents the surface brightness map of the stellar disk, as obtained by IFU observation. The middle panel shows the stellar disk as observed in Spitzer 3.6 μm data. The right panel indicates our simulated intensity distribution. The crosses in each panel indicate the center of the galaxy.
