    A Double Main Sequence in the Globular Cluster NGC 6397
    High-precision multi-band Hubble Space Telescope (HST) photometry reveals that the main sequence of the globular cluster NGC 6397 splits into two components...
  • Publication
    A double stellar generation in the globular cluster NGC 6656 (M 22). Two stellar groups with different iron and s-process element abundances
    We present a chemical abundance analysis based on high resolution UVES spectra of seventeen bright giant stars in the Globular Cluster (GC) M 22. We obtained an...
  • Publication
    A Duality in the Origin of Bulges and Spheroidal Galaxies
    Studying the resolved stellar populations of the different structural components that build massive galaxies directly unveils their assembly history. We aim at...
  • 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 dust-obscured massive maximum-starburst galaxy at a redshift of 6.34
    Massive present-day early-type (elliptical and lenticular) galaxies probably gained the bulk of their stellar mass and heavy elements through intense, dust...
  • Publication
    A dusty protocluster surrounding the binary galaxy HerBS-70 at z = 2.3
    We report on deep SCUBA-2 observations at 850 $\mu$m and NOrthern Extended Millimetre Array (NOEMA) spectroscopic measurements at 2 mm of the environment...
  • Publication
    A dusty star-forming galaxy at z = 6 revealed by strong gravitational lensing
    Since their discovery, submillimetre-selected galaxies1,2 have revolutionized the field of galaxy formation and evolution. From the hundreds of square degrees...
  • 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 dynamic view of V Hydrae. Monitoring of a spectroscopic-binary AGB star with an alkaline jet
    Context. The well studied carbon star V Hydrae is known to exhibit a complex asymmetric environment made of a dense equatorial wind and high-velocity outflows...
