Edge-on and face-on density maps for a typical galaxy of our catalogue (G1 in Table 1) in simulation S230A (upper panels). The color bar shows stellar density in units of 10¹⁰ M_⊙ kpc^-3. The middle and lower panels show the age gradients and star formation rate for stars in the central spheroid (green), the disc (blue), the stellar halo (red). The solid black line in the lower panel correspond to the total star formation rate.
