The use of integral field spectroscopy is since recently allowing to measure the emission line
fluxes of an increasingly large number of star-forming galaxies, both locally and at high …

Simple relations for deriving the oxygen abundance in H ii regions with intensities of the
three strong emission lines R 2, R 3, and N 2 (R calibration) or S 2, R 3, and N 2 (S …

Observations of evolution in the dust-to-metal ratio allow us to constrain the dominant dust
processing mechanisms. In this work, we present a study of the dust-to-metal and dust-to …

We investigate the oxygen and nitrogen abundance distributions across the optical disks of
130 nearby late-type galaxies using around 3740 published spectra of H ii regions. We use …

New improved empirical calibrations for the determination of electron temperatures and
oxygen and nitrogen abundances in H ii regions from the strong emission lines of oxygen …

We suggest a new way of determining abundances and electron temperatures in H ii
regions from strong emission lines. Our approach is based on the standard assumption that …

We discuss chemical enrichments of∼ 4000 Sloan Digital Sky Survey early-type galaxies
using as tracers a large variety of element abundance ratios, namely [C/Fe],[N/Fe],[O/Fe],[Mg …

We present the first results from MMT and Keck spectroscopy for a large sample of
$0.1\leqslant z\leqslant 1$ emission-line galaxies selected from our narrowband imaging in …

Aims. The chemical evolution of galaxies on a cosmological timescale is still a matter of
debate despite the increasing number of available data provided by spectroscopic surveys …

We construct maps of the oxygen abundance distribution across the discs of 88 galaxies
using Calar Alto Legacy Integral Field Area survey (CALIFA) Data Release 2 (DR2) spectra …
