    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 -...

    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...

    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...

    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)...

    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...

    Absence of nuclear polycyclic aromatic hydrocarbon emission from a compact starburst: The case of the type-2 quasar Mrk 477
    Mrk 477 is the closest type-2 quasar, at a distance of 163 Mpc. This makes it an ideal laboratory for studying the interplay between nuclear activity and star...
