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 …

Diffuse ionized gas (DIG) is prevalent in star-forming galaxies. Using a sample of 365 nearly
face-on star-forming galaxies observed by Mapping Nearby Galaxies at APO, 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 characterised the oxygen abundance radial distribution of a sample of 102 spiral
galaxies observed with VLT/MUSE using the O3N2 calibrator. The high spatial resolution of …

We measured gas-phase metallicity, ionisation parameter, and dust extinction for a
representative sample of 1795 local star-forming galaxies using integral field spectroscopy …

We present a new model for the evolution of gas phase metallicity gradients in galaxies from
first principles. We show that metallicity gradients depend on four ratios that collectively …

Radial abundance gradients provide sound constraints for chemo-dynamical models of
galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their …

I review the spatially resolved spectroscopic properties of low-redshift star-forming galaxies
(and their retired counterparts) using results from the most recent optical integral field …

We use FIRE-2 simulations to examine 3D variations of gas-phase elemental abundances of
[O/H],[Fe/H], and [N/H] in 11 MW and M31-mass galaxies across their formation histories at …

Using integral field spectroscopic data of 24 nearby spiral galaxies obtained with the Multi
Unit Spectroscopic Explorer, we derive empirical calibrations to determine the metallicity of …
