Fig. 2


Metallicity maps of the simulated galaxy in Galactic coordinates. Top panel: disk and classical bulge stars are included; bottom panel: disk stars are only shown (see text for the choice of the initial metallicity of disk and classical bulge stars). In both panels, only stars with | x | ≤ 2.5 kpc and | y | ≤ 3 kpc from the galaxy center have been selected. Some contour levels for the metallicity maps are also reported with values given in the maps.

This figure is made of several images, please see below:
