Scientific paper

Recent results have shown that nuclear, gas-phase oxygen abundances are depressed in strongly interacting galaxies. We present some of the first observed radial metallicity gradients of strongly interacting galaxies, using multi-object Keck spectroscopy. Flattened gradients, and comparison to numerical simulations, confirm that lowered nuclear abundances are caused by interaction-driven gas inflows.
