ABSTRACT Cosmological simulations provide much of the theoretical framework within which we interpret extragalactic observations. However, even if a given simulation reproduces the integrated properties of galaxies well, it may not reproduce the detailed structures of individual galaxies. Comparisons between the 2D light distributions of simulated and observed galaxies – particularly in the dwarf regime, where key processes like tidal perturbations and baryonic feedback most strongly influence galaxy structure – t…
