The evolution of the content of heavy elements in galaxies, the relative chemical
abundances, their spatial distribution, and how these scale with various galactic properties …

We report observations from the Hubble Space Telescope (HST) of Cepheid variables in the
host galaxies of 42 Type Ia supernovae (SNe Ia) used to calibrate the Hubble constant (H 0) …

The relationships between stellar mass, gas-phase metallicity and star-formation rate (ie the
mass–metallicity, MZR, and the fundamental metallicity relation, FMR) in the local Universe …

We present detections of [O iii] λ4363 and direct-method metallicities for star-forming
galaxies at z= 1.7–3.6. We combine new measurements from the MOSFIRE Deep Evolution …

We derive new empirical calibrations for strong-line diagnostics of gas phase metallicity in
local star forming galaxies by uniformly applying the Te method over the full metallicity range …

We review the properties of the established Scaling Relations (SRs) of galaxies and active
galactic nuclei (AGN), focusing on their origin and expected evolution back in time, providing …

The chemical abundances of spiral galaxies, as probed by H ii regions across their disks,
are key to understanding the evolution of galaxies over a wide range of environments. We …

We present a tutorial on the determination of the physical conditions and chemical
abundances in gaseous nebulae. We also include a brief review of recent results on the …

We present an updated version of the mass–metallicity (MZ) relation using integral field
spectroscopy data obtained from 734 galaxies observed by the CALIFA survey. These …

We present a spatially resolved H ii region study of the gas-phase metallicity, ionization
parameter, and interstellar medium (ISM) pressure maps of six local star-forming and face …
