    On the formation of globular cluster systems in a hierarchical Universe
    We have investigated the formation of globular cluster (GC) systems in the fiducial semi-analytic model of galaxy formation of Cole et al., by assuming that GCs...
  • Publication
    On the formation of massive stellar clusters
    Here we model a star forming factory in which the continuous creation of stars results in a highly concentrated, massive (globular cluster-like) stellar system...

    On the Formation of Massive Stellar Clusters
    Here we report on the properties of the star forming factory, in which the continuous creation of stars results into a highly concentrated, massive (globular...
  • Publication
    On the Heating Efficiency Derived from Observations of Young Super Star Clusters in M82
    Here, we discuss the mechanical feedback that massive stellar clusters provide to the interstellar medium of their host galaxy. We apply an analytic theory...
  • Publication
    On the importance of the few most massive stars: The ionizing cluster of NGC 588
    We present the results of a double analysis of the ionizing cluster in NGC 588, a giant HII region (GHR) in the outskirts of the nearby galaxy M 33. For this...

    On the Influence of the Environment on the Star Formation Rates of a Sample of Galaxies in Nearby Compact Groups
    We present the results of a study of the star formation rates (SFRs) of a sample of disk galaxies in nearby compact groups compared with the SFRs of a sample of...
  • Publication
    On the Ionizing Continuum in Active Galactic Nuclei: Clues from the Infrared Space Observatory
    The Infrared Space Observatory (ISO) coronal line spectrum of the brightest Seyfert galaxies from the CfA sample is presented and modeled. ISO observations of...
  • Publication
    On the lensed blazar B0218+357
    We present an optical spectrum (λλ4000-10 500) of the lensed blazar B0218+357 secured at the 10 m GTC and aimed to investigate and clarify the properties of...
  • Publication
    On the Metallicity of Star-forming Dwarf Galaxies
    We construct three extremely different scenarios of the star formation histories applicable to a sample of dwarf galaxies, based on either their present...
