Metallicity has followed local gravitational potential of galaxies since z=3
The gas velocity width in DLA and GRB host galaxies falls with impact parameter at the slope predicted if metallicity traces local gravitational potential, supporting a local mass-metallicity relation out to 40-60 kpc back to z~3.
