(IOP PUBLISHING LTD, 2012-02-20)We present long-slit spectrophotometry considering the presence of thermal inhomogeneities (t(2)) of two H II regions in the Small Magellanic Cloud (SMC): NGC 456 and NGC 460. Physical conditions and chemical abundances ...
-
(EDP Sciences, 2015)We present a study of the HII regions in the galaxy NGC 6754 from a two pointing mosaic comprising 197 637 individual spectra, using integral field spectroscopy recently acquired with the MUSE instrument during its Science ...
-
(The American Astronomical Society, 2015-01-10)We present a new method for inferring the metallicity (Z) and ionization parameter (q) of H ii regions and star-forming galaxies using strong nebular emission lines (SELs). We use Bayesian inference to derive the joint and ...
-
(EDP SCIENCES, 2016)We study, for the first time in a statistically significant and well-defined sample, the relation between the outer-disk ionized-gas metallicity gradients and the presence of breaks in the surface brightness profiles of ...
-
(Royal Astronomical Society, 2015)MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is a 6-yr Sloan Digital Sky Survey (SDSS-IV) survey that will obtain spatially resolved spectroscopy from 3600 to 10 300 Å for a representative sample of over ...
-
(ESO, 2016-03)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 consistent with star formation. This type of analysis allowed ...
-
(WILEY-BLACKWELL PUBLISHING, 2009)We present spectra of six luminous quasars at z ∼ 2, covering rest wavelengths 1600−3200 Å. The fluxes of the UV Fe II emission lines and MgII λ2798 doublet, the line widths of Mg II and the 3000 Å luminosity were obtained ...
-
(2016)We present an analysis of the gas-phase oxygen abundances of a sample of 28 galaxies in the local Universe (z < 0.02) hosting Type Ia supernovae (SNe Ia). The data were obtained with the 4.2 m William Herschel Telescope. ...
