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…
