Ahn et al found two ultra-compact dwarf galaxies, VUCD3 and M59cO, with supermassive black holes. The findings suggest that these dwarf galaxies are likely tiny leftovers of larger galaxies that were stripped of their outer layers after colliding into other, larger galaxies Messier 87 and Messier 59, respectively.
