Current (z = 0) stellar mass (upper row) and redshift of accretion (lower row) of the six most massive accreted progenitors of the four Auriga MW-like galaxies studied here. The stellar mass of the in situ component at z = 0 is also indicated for comparison, as it is the redshift of accretion of the smaller progenitors. The left column displays these properties as calculated within the entire galaxy (i.e. < R₂₀₀), while the right column for the solar vicinity region (see Section 3.1). In the bottom panels, the circles (shaded regions) indicate the (range of) redshift when 50% (5–90%) of the stellar particles from a progenitor were accreted by the main galaxy. The accreted galaxies with a surviving progenitor with more than 1% of the initial mass of the progenitor at z = 0 are indicated with an open circle.
