    The halo+cluster system of the Galactic globular cluster NGC 1851
    NGC 1851 is surrounded by a stellar component that extends more than 10 times beyond the tidal radius. Although the nature of this stellar structure is not...

    The Herschel Multi-tiered Extragalactic Survey: SPIRE-mm photometric redshifts
    We investigate the potential of submm-mm and submm-mm-radio photometric redshifts using a sample of mm-selected sources as seen at 250, 350 and 500μm by the...
  • Publication
    The homogeneity of chemical abundances in H II regions of the Magellanic Clouds
    We use very deep spectra obtained with the Ultraviolet-Visual Echelle Spectrograph at the Very Large Telescope to derive physical conditions and chemical...

    The Hot R Coronae Borealis Star DY Centauri is a Binary
    The remarkable hot R Coronae Borealis (RCB) star DY Cen is revealed to be the first and only binary system to be found among the RCB stars and their likely...

    The HST/ACS star formation history of the Tucana dwarf spheroidal galaxy: clues from the horizontal branch
    We report a new star formation history for the Tucana dwarf spheroidal galaxy, obtained from a new look at a deep HST/ACS colour-magnitude diagram. We combined...

    The Hubble Catalog of Variables (HCV)
    Aims: Over its lifetime and despite not being a survey telescope, the Hubble Space Telescope (HST) has obtained multi-epoch observations by multiple, diverse...

    The Hubble Space Telescope UV Legacy Survey of galactic globular clusters - II. The seven stellar populations of NGC 7089 (M2)⋆
    We present high-precision multiband photometry for the globular cluster (GC) M2. We combine the analysis of the photometric data obtained from the Hubble Space...

    The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters - IV. Helium content and relative age of multiple stellar populations within NGC 6352
    In this paper, we combine Wide Field Camera3/UVIS F275W, F336W, and F438W data from the `UV Legacy Survey of Galactic Globular Clusters: Shedding Light on Their...
  • Publication
    The Hubble Space Telescope UV Legacy Survey of Galactic globular clusters - IX. The Atlas of multiple stellar populations
    We use high-precision photometry of red-giant-branch (RGB) stars in 57 Galactic globular clusters (GCs), mostly from the `Hubble Space Telescope (HST) UV Legacy...
