    The variable sources responsible for the photometric behaviour of OJ 287 in the IR-optical-UV region during 1993-1996
    An analysis is performed of multicolour observations of OJ 287 carried out during the OJ-94 Project. It is found that in the optical region the variable sources...

    The variable X-ray light curve of GRB 050713A: the case of refreshed shocks
    We present a detailed study of the spectral and temporal properties of the X-ray and optical emission of GRB050713a up to 0.5 day after the main Gamma Ray Burst...

    The Variable-Star Population in Phoenix: Coexistence of Anomalous and Short-Period Classical Cepheids and Detection of RR Lyrae Variables
    We present the results of a search for variable stars in the Local Group dwarf galaxy Phoenix. Nineteen Cepheids, six candidate long-period variables, one...

    The Variation of Integrated Star Initial Mass Functions among Galaxies
    The integrated galaxial initial mass function (IGIMF) is the relevant distribution function containing the information on the distribution of stellar remnants...
  • Publication
    The velocity field of the Lyra complex
    Context. The formation of cosmic structures culminates with the assembly of galaxy clusters, a process that is quite different from cluster to cluster. Aims: We...

    The Veritas and Themis asteroid families: 5-14 μm spectra with the Spitzer Space Telescope
    Spectroscopic investigations of primitive asteroid families constrain family evolution and composition and conditions in the solar nebula, and reveal...

    The Vertical Metallicity Gradient of the Milky Way Disk: Transitions in [α/Fe] Populations
    Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined the vertical metallicity gradient in the...

    The vertical stellar distribution in NGC 6504: Detection of a thick disk
    The vertical stellar distribution of the edge-on spiral NGC 6504 is examined in seven bands (U, B, R, I, J, H, K) by fitting model distributions to the light...

    The vertical structure of the spiral galaxy NGC 3501: first stages of the formation of a thin metal-rich disc
    We trace the evolution of the edge-on spiral galaxy NGC 3501, making use of its stellar populations extracted from deep integral-field spectroscopy MUSE...
