Gas-phase metallicity break radii of star-forming galaxies in IllustrisTNG

We present radial gas-phase metallicity profiles, gradients, and break radii at redshift z = 0 - 3 from the TNG50-1 star-forming galaxy population. These metallicity profiles are characterized by an emphasis on identifying the steep inner gradient and flat outer gradient. From this, the break radius, r_{\rm Break}, is defined... Show more
