    A tidal tale: detection of several stellar streams in the environment of NGC 1052
    The possible existence of two dark-matter-free galaxies (NGC 1052-DF2 and NGC 1052-DF4) in the field of the early-type galaxy NGC 1052 presents a challenge to...

    A Two Micron All Sky Survey View of the Sagittarius Dwarf Galaxy. VI. s-Process and Titanium Abundance Variations Along the Sagittarius Stream
    We present high-resolution spectroscopic measurements of the abundances of the α element titanium (Ti) and s-process elements yttrium (Y) and lanthanum (La) for...

    A unified model for age-velocity dispersion relations in Local Group galaxies: disentangling ISM turbulence and latent dynamical heating
    We analyse age-velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina (M* ˜ 106 M⊙)...

    A unified picture of breaks and truncations in spiral galaxies from SDSS and S4G imaging
    The mechanism causing breaks in the radial surface-brightness distribution of spiral galaxies is not yet well known. Despite theoretical efforts, there is not a...

    A very dark stellar system lost in Virgo: kinematics and metallicity of SECCO 1 with MUSE
    We present the results of VLT-MUSE (Very Large Telescope-Multi Unit Spectroscopic Explorer) integral field spectroscopy of SECCO 1, a faint, star-forming...

    A Very Small Array search for the extended Sunyaev-Zel'dovich effect in the Corona Borealis supercluster
    We present interferometric imaging at 33 GHz of the Corona Borealis supercluster, using the extended configuration of the Very Small Array. A total area of 24...

    A Virtual Observatory Census to Address Dwarfs Origins (AVOCADO). I. Science goals, sample selection, and analysis tools
    Context. Even though they are by far the most abundant of all galaxy types, the detailed properties of dwarf galaxies are still only poorly characterised -...
  • Publication
    A VLT/FORS2 spectroscopic survey of individual stars in a transforming dwarf galaxy
    Understanding the properties of dwarf galaxies is important not only to put them in their proper cosmological context, but also to understand the formation and...

    A VLT/VIMOS view of two Planck multiple-cluster systems: Structure and galaxy properties
    We analysed spectroscopic data obtained with VLT/VIMOS for two multiple-cluster systems, PLCKG214.6+36.9 and PLCKG334.8−38.0, discovered by Planck via their...
