Inflow-driven galaxy evolution - I. Revealing the physics of the fundamental metallicity relation
Kai Wang, Carlton Baugh, N. F. Boardman +11
We present a unified physical framework for the fundamental metallicity relation (FMR), based on the mass-continuity equations. The FMR is not merely the anti-correlation between s…
Beyond the Fundamental Metallicity Relation: galaxy sizes encode the link between inflow and metallicity
N. F. Boardman, V. Wild, D. Scholte +3
Gas-phase chemical abundances are key observable consequences of galaxy evolution, being intrinsically tied to galaxy formation histories. Gas metallicity rises with increasing ste…
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…
SDSS-IV MaNGA: Stellar rotational support in disk galaxies vs. central surface density and stellar population age
Xiaohan Wang, Yifei Luo, S. M. Faber +10
We investigate how the stellar rotational support changes as a function of spatially resolved stellar population age () and relative central stellar surface density ($…
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…
Chemical evolution of local post-starburst galaxies: Implications for the mass-metallicity relation
Ho-Hin Leung, Vivienne Wild, Michail Papathomas +5
We use the stellar fossil record to constrain the stellar metallicity evolution and star-formation histories of the post-starburst (PSB) regions within 45 local post-starburst gala…
