Simulated Fornax develops a stellar halo similar to the real Fornax. The so-called “halo” of Fornax (Yang et al. 2022) is the excess of stars in the outer part of the galaxy with respect to a simple Sésics fit (red dotted line). The whole profile is described well by a sum of two Sésic profiles (full red line). The simulated Fornax is initially described by a simple Sésic profile (black dotted line), but eventually develops a profile with a “halo” (full black line) like the real galaxy has.
