Fig. 5.


Top: representative galaxies of different stellar masses: a giant elliptical (M ∼ 2.5 × 1011M), a Milky Way-like galaxy (M ∼ 2.5 × 1010M), a UDG and dwarf galaxy (M ∼ 108M). All galaxies are shown to the same physical scale and a similar depth in surface brightness. Bottom: stellar mass density profiles of the same galaxies. The coloured ticks in the upper x-axis mark the location of Re. Similar ticks in the lower x-axis mark the location of R1.
