DOI: 10.1093/mnras/stab1018
Abstract: We apply fossil record techniques to the CALIFA sample to study how galaxies in the Local Universe have evolved in terms of their chemical content. We show how the stellar metallicity and the mass–metallicity relation… read more here.

DOI: 10.1093/mnras/stab868
Abstract: In addition to the well-known gas phase mass-metallicity relation (MZR), recent spatially-resolved observations have shown that local galaxies also obey a mass-metallicity gradient relation (MZGR) whereby metallicity gradients can vary systematically with galaxy mass. In… read more here.

DOI: 10.1093/mnras/stac906
Abstract: Observed and simulated galaxies exhibit correlations between stellar mass, metallicity and morphology. We use the eagle cosmological simulation to examine the origin of these correlations for galaxies in the stellar mass range $10^9~\rm {M_\odot }… read more here.

DOI: 10.1093/mnras/stx2451
Abstract: We present a comprehensive study of the relations between gas kinematics, metallicity and stellar mass in a sample of 82 gamma-ray burst (GRB)-selected galaxies using absorption and emission methods. We find the velocity widths of… read more here.

DOI: 10.1093/mnras/sty2380
Abstract: The gas-phase metallicity of low-mass galaxies increases with increasing stellar mass (M*) and is nearly constant for high-mass galaxies. Theory suggests that this tight mass–metallicity relationship is shaped by galactic outflows removing metal-enriched gas from… read more here.

DOI: 10.1093/mnrasl/slad046
Abstract: Deriving oxygen abundances from the electron temperature (hereafter the Te-method) is the gold-standard for extragalactic metallicity studies. However, unresolved temperature fluctuations within individual H ii regions and across different H ii regions throughout a galaxy can bias… read more here.
