    The ratio of pattern speeds in double-barred galaxies
    We have obtained two-dimensional velocity fields in the ionized gas of a set of eight double-barred galaxies, at high spatial and spectral resolution, using...
  • Publication
    The Realm of the Galactic Globular Clusters and the Mass of Their Primordial Clouds
    By adopting the empirical constraints related to the estimates of helium enhancement ({{Δ }}Y), the present mass ratio between first and second stellar...
  • Publication
    The Recent Star Formation History of NGC 5102
    We present Hubble Space Telescope photometry of young stars in NGC 5102, a nearby gas-rich post-starburst S0 galaxy with a bright young stellar nucleus. We use...
  • Publication
    The Recent Stellar Archeology of M31—The Nearest Red Disk Galaxy
    We examine the star-forming history of the M31 disk during the past few hundred Myr. The luminosity functions (LFs) of main-sequence stars at distances R GC >...
  • Publication
    The recurrent impact of the Sagittarius dwarf on the star formation history of the Milky Way
    Satellites orbiting disk galaxies can induce phase space features such as spirality, vertical heating and phase-mixing in their disks. Such features have also...

    The red giant branch phase transition: Implications for the RGB luminosity function bump and detections of Li-rich red clump stars
    We performed a detailed study of the evolution of the luminosity of He-ignition stage and of the red giant branch bump luminosity during the red giant branch...
  • Publication
    The red giant branches of Galactic globular clusters in the [(V-I)0,MV] plane: metallicity indices and morphology
    The purpose of this study is to carry out a thorough investigation of the changes in morphology of the red giant branch (RGB) of Galactic globular clusters (GGC...
  • Publication
    The redshift and broad-band spectral energy distribution of NRAO 150
    Context. NRAO 150 is one of the brightest radio and mm AGN sources in the northern sky, and is an interesting source to study extreme relativistic jet phenomena...
  • Publication
    The Redshift Distribution of Flat-Spectrum Radio Sources
    The redshift distribution of flat-spectrum radio sources with 5 GHz flux densities S5>~5 mJy is a key component in using current radio lens surveys to probe the...
