    A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE): XVIII. Reconstructing the star formation history of early-type galaxies through the combination of their UV and Hα emission
    We reconstructed the star formation histories of seven massive (M ⋆ ≳ 10 10 M ⊙) early-type galaxies (ETGs) in the Virgo cluster by analysing their spatially...
  • Publication
    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...
  • Publication
    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...
  • Publication
    A wide-area view of the Phoenix dwarf galaxy from Very Large Telescope/FORS imaging
    We present results from a wide-area photometric survey of the Phoenix dwarf galaxy, one of the rare dwarf irregular/dwarf spheroidal transition-type galaxies...
  • Publication
    A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour
    Context. Blazars are beamed active galactic nuclei (AGNs) known for their strong multi-wavelength variability on timescales ranging from years down to minutes...
  • Publication
    A young, dusty, compact radio source within a Lyα halo
    We report here on the discovery of a red quasar, J004929.4+351025.7 at a redshift of z = 2.48, situated within a large Lyα emission-line halo. The radio...

    A959 galaxies r' magnitude and radial velocities (Boschin+, 2009)
    Multi-object spectroscopic observations of A959 were carried out at the TNG telescope in December 2006. We used DOLORES/MOS with the LR-B Grism 1. (1 data file)...
  • Publication
    Abell 1758N from an optical point of view: new insights on a merging cluster with diffuse radio emission
    Context. The mechanisms producing the diffuse radio emission in galaxy clusters, and in particular their connection with cluster mergers, are still debated...
