Fig. 3.
Accretion classes for the simulated sample of ETGs. Top: median stellar-mass-density profiles for each of the four classes defined in Sect. 4.1. The black lines show the median total density profiles, and the red and blue lines show the median density profiles of the in-situ and the ex-situ stars respectively. The shaded regions show the quartiles of the distributions. Bottom: median cumulative stellar-mass-fraction profiles for the in-situ and ex-situ components in the four accretion classes. The shaded regions show the quartiles of the distributions.
