The distribution of metals within a galaxy traces the baryon cycle and the buildup of galactic
disks, but the detailed gas phase metallicity distribution remains poorly sampled. We have …

We present intermediate-resolution optical spectrophotometry of 65 galaxies obtained in
support of the Spitzer Infrared Nearby Galaxies Survey (SINGS). For each galaxy we obtain …

We develop a model for the regulation of galactic star formation rates Σ SFR in disk galaxies,
in which interstellar medium (ISM) heating by stellar UV plays a key role. By requiring that …

We use high signal-to-noise ratio spectra of 20 H II regions in the giant spiral galaxy M101 to
derive electron temperatures for the H II regions and robust metal abundances over radii R …

Using integrated optical spectrophotometry for 412 star-forming galaxies at z~ 0, and fiber-
aperture spectrophotometry for 120,846 SDSS galaxies at z~ 0.1, we investigate the Hα …

Context. We study the role of radial migration of stars on the chemical evolution of the Milky
Way disk. Aims. We are interested in the impact of that process on the local properties of 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 present the results of a systematic study of mid-IR spectra of Galactic regions,
Magellanic H ii regions, and galaxies of various types (dwarf, spiral, starburst), observed by …

Recent results comparing interacting galaxies to the mass–metallicity relation show that their
nuclear oxygen abundances are unexpectedly low. We present analysis of N …

We study the physical properties of the ionized gas in local discs using the sample of 38
nearby∼ 108.5–11.2 M⊙ Star-Forming Main-Sequence (SFMS) galaxies observed so far as …
