Fraction of the stellar mass from accreted origin as a function of stellar mass (left) and amount of stellar mass accreted as a function of virial halo mass (right) for our samples. We show the medians calculated in three different M200 ranges, (< 8 × 1011), (8 × 1011 − 1.5 × 1012), and (> 1.5 × 1012 M), chosen to include a fair number of galaxies in each bin. In general, spheroid-dominated objects have a larger contribution from accreted stars, but the overlap between the samples is substantial. We highlight the presence of mostly-disc and intermediate galaxies with a large accreted mass MMergers > 1010 M as well as the presence of three spheroid-dominated galaxies with less than 3% of their mass from accretion.
