Gas-phase oxygen gradients in strongly interacting galaxies. I. Early-stage interactions
A consensus is emerging that interacting galaxies show depressed nuclear gas metallicities compared to isolated star-forming galaxies. Simulations suggest that this nuclear underabundance is caused by interactioninduced inflow of metal-poor gas and that this inflow concurrently flattens the radial metallicity gradients in strongly interacting galaxies. We present metallicities of over 300 H II regions in a sample of 16 spirals that are members of strongly interacting galaxy pairs with mass...[Show more]
