Chemical enrichment in LINERs from MaNGA: II. Characterizing the shape of the radial metallicity gradients
Chemical enrichment in LINERs from MaNGA: II. Characterizing the shape of the radial metallicity gradients

The AGN feed(back) process alters the shape of radial metallicity gradients depending on how evolved the galaxy is, and which is the dominant source for gas kinematics.

A departure from the mass-metallicity relation in merging galaxies due to an infall of metal-poor gas
A departure from the mass-metallicity relation in merging galaxies due to an infall of metal-poor gas

Mergen-driven infall of metal-poor gas causes metallicity dillutation but enhances star formation, explaining observed properties of (U)LIRGs.
