    Structure of Abell 1995 from optical and X-ray data: a galaxy cluster with an elongated radio halo
    Context. Abell 1995 is a puzzling galaxy cluster hosting a powerful radio halo, but it has not yet been recognized as a obvious cluster merger, as usually...
  • Publication
    Structure, kinematics and chemical enrichment patterns after major gas-rich disc-disc mergers
    We used an N-body smoothed particle hydrodynamics algorithm, with a detailed treatment of star formation, supernovae feedback and chemical enrichment, to...

    Study of star-forming galaxies in SDSS up to redshift 0.4. I. Metallicity evolution
    Context: The chemical composition of the gas in galaxies over cosmic time provides a very important tool for understanding galaxy evolution. Although there are...

    Study of stellar populations in the bulges of barred galaxies
    Aims: We wish to determine the influence of bars on the building of galaxy bulges through analysis of ages and metallicities derived from stellar absorption...

    Study of the Extended Narrow-Line Region in the Host Galaxy of the Lensed QSO 2237+0305 (z = 1.69)
    The detection of spatially extended line emission in multiply imaged QSOs offers a new possibility to study the properties (kinematics and structure) of the...

    Study of the thermal and nonthermal emission components in M 31: the Sardinia Radio Telescope view at 6.6 GHz
    Context. The Andromeda galaxy is the best-known large galaxy besides our own Milky Way. Several images and studies exist at all wavelengths from radio to hard X...
