Luminosity of MATLAS UDGs nuclei as compared with the ones of the MATLAS dwarfs. Top: contribution of the nucleus to the total luminosity of the galaxy as a function of the galaxy absolute magnitude. Bottom: distribution of absolute magnitude of the nuclei of the MATLAS dwarfs and UDGs. No difference in luminosity is visible between the UDGs and dwarfs nuclei.
