Stellar mass-size relation for low M* galaxies

DOI

We reliably extend the stellar mass-size relation over 0.2<=z=10^10.3^M_{sun} and flattens at lower masses, regardless of whether quiescence is selected based on star-formation activity, rest-frame colours, or structural characteristics. This flattening occurs at sizes of ~1kpc at z=10^9.5^M{sun} and quiescent galaxies with stellar masses>=10^10.3^M{sun} have undergone significant size growth since z~2, as expected; however, low mass galaxies have not. Finally, we supplement our data with predominantly quiescent dwarf galaxies from the core of the Fornax cluster, showing that the stellar mass-size relation is continuous below 10^7^M{sun}_, but a more complicated functional form is necessary to describe the relation.
