Left panels: location of the SC birth-site assuming a Galactic (GAL, blue filled histogram) or extragalactic (EXT, red empty histogram) origin. From top to bottom, panels correspond to infall time intervals (0–3), (3–5), and (5–10) Gyr ago, respectively. We include in the plot the distribution of current locations of MW satellites (black dashed histogram). All histograms are normalized to the total number of objects in each sample. Central (right) panels: combined surface distribution of initial mass and galactocentric distance in the case of a galactic (extragalactic) origin, assuming the same infall time ranges as in the left panels.
