Plot of universal stellar mass-metallicity relation from Kirby et al. (2013; blue solid line) with its rms (blue dashed lines). On the x-axis is plotted the logarithm of the stellar mass in units of solar mass. Left: data from this work (red circles), but excluding star forming and low S/N galaxies. Right: full sample from this work. Star forming galaxies are shown as yellow upward pointing triangles, while low S/N galaxies are gray downward pointing triangles. Shown is a comparison of our results with galaxies from other works: LG dwarfs (blue; Kirby et al. 2013), Cen A dwarfs (pink; Müller et al. 2021b), galaxies in Fornax and Virgo (green; Fahrion et al. 2021), nucleated dwarf LTGs (purple; Fahrion et al. 2022), and UDGs in the Coma cluster (orange; Chilingarian et al. 2019). Bottom: residual plots (i.e., metallicity dwarf-metallicity fit). The blue dashed lines indicate the rms of the fit from Kirby et al. (2013). The LG dwarf metallicities from Kirby et al. (2013) are iron metallicities ([Fe/H]), while all other data points show total metallicities ([M/H]).
