We review the use of emission lines for understanding galaxy evolution, focusing on
excitation source, metallicity, ionization parameter, ISM pressure, and electron density. We …

This paper reviews a wide range of questions in astrophysics and cosmology that can be
answered by astronomical observations in the far-IR to millimeter wavelength range and …

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 …

Using observations from the MOSFIRE Deep Evolution Field survey, we investigate the
physical conditions of star-forming regions in z∼ 2.3 galaxies, specifically the electron …

We present the largest and most homogeneous catalog of H ii regions and associations
compiled so far. The catalog comprises more than 7000 ionized regions, extracted from 306 …

Analysis of emission lines in gaseous nebulae yields direct measures of physical conditions
and chemical abundances and is the cornerstone of nebular astrophysics. Although the …

We present a first study based on the analysis of the DEep Spectra of Ionized REgions Data
base (DESIRED). This is a compilation of 190 high signal-to-noise ratio optical spectra of …

We measured the gas abundance profiles in a sample of 122 face-on spiral galaxies
observed by the CALIFA survey and included all spaxels whose line emission was …

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 …
