  • Publication
    A detailed look at chemical abundances in the Magellanic Clouds
    We determine elemental abundances of He, N, O, Ne, S, and Ar in Magellanic Cloud planetary nebulae (PNe) using direct methods and a large set of observed ions...
  • Publication
    A detailed look at the stellar populations in green valley galaxies
    The green valley (GV) represents an important transitional state from actively star-forming galaxies to passively evolving systems. Its traditional definition...
  • Publication
    A detailed two-dimensional stellar population study of M32
    We present integral field spectroscopy of the 9×12arcsec2 circumnuclear region of M32 obtained with the 2D_FIS fibre optics spectrographs installed at the 4.2-m...
  • Publication
    A diffuse tidal dwarf galaxy destined to fade out as a "dark galaxy"
    We have explored the properties of a peculiar object detected in deep optical imaging and located at the tip of an H I tail emerging from Hickson Compact Group...
  • Publication
    A distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
    The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and...
  • Publication
    A Dust Lane Leading the Galactic Bar at Negative Galactic Longitudes
    Comparing the different wavelengths of the DIRBE integrated surface brightness maps at positive and negative Galactic longitudes on the plane near the Galactic...
  • Publication
    A dwarf-dwarf merger and dark matter core as a solution to the globular cluster problems in the Fornax dSph
    The five globular clusters (GCs) of the Fornax dwarf spheroidal galaxy are puzzling for two reasons; the mass in GCs is high with respect to the galaxy's old...
  • Publication
    A dynamical view on stellar metallicity gradient diversity across the Hubble sequence with CALIFA
    We analyse radial stellar metallicity and kinematic profiles out to 1Re in 244 CALIFA galaxies ranging from morphological type E to Sd, to study the...
  • Publication
    A Far-infrared Spectroscopic Survey of Intermediate Redshift (Ultra) Luminous Infrared Galaxies
    We present Herschel far-IR photometry and spectroscopy as well as ground-based CO observations of an intermediate redshift (0.21 1 is already significant by z ~...
