Scaling relations of dwarf galaxies: central surface brightness (top-left), effective surface brightness (top-right), effective radius (bottom-left), and mean metallicity (bottom-right) vs. absolute luminosity. We show Local Group dwarfs (gray dots, McConnachie 2012), previously studied Cen A dwarfs (blue squares and purple triangles, Crnojević et al. 2010, 2012, 2019; Müller et al. 2017a), and our newly confirmed members (red circles).
