The competing effects of recent and long-term star formation histories on oxygen, nitrogen, and stellar metallicities
Nicholas Fraser Boardman, Vivienne Wild, Natalia Vale Asari +1
The fundamental metallicity relation (FMR) - the three-way trend between galaxy stellar masses, star-formation rates (SFRs) and gaseous metallicities - remains amongst the most stu…

A tight N/O-potential relation in star-forming galaxies
Nicholas Fraser Boardman, Vivienne Wild, Natalia Vale Asari
We report a significantly tighter trend between gaseous N/O and (a proxy for gravitational potential) than has previously been reported between gaseous metallicity and $M…

SDSS-IV MaNGA: how do star-formation histories affect gas-phase abundances?
Nicholas Fraser Boardman, Vivienne Wild, Kate Rowlands +2
Gas-phase abundances in galaxies are the products of those galaxies' evolutionary histories. The star-formation history (SFH) of a region might therefore be expected to influence t…
