Spiral galaxies with flat radial abundance gradients at large radii
We consider the oxygen abundance distributions for a sample of massive (log(M★/M⊙) ≳ 10) spiral galaxies from the Mapping Nearby Galaxies at the Apache Point Observatory (MaNGA) survey in which the radial abundance gradient flattens to a constant value outside of the outer break radius, Rb, outer.
