Astrophysical: Star clusters

  • Publication
    On biases in the predictions of stellar population synthesis models
    Sampling fluctuations in stellar populations give rise to dispersion in observables when a small number of sources contribute effectively to the observables...
  • Publication
    On emission-line spectra obtained from evolutionary synthesis models. I. Dispersion in the ionising flux and Lowest Luminosity Limits
    Stellar clusters with the same general physical properties (e.g., total mass, age, and star-formation mode) may have very different stellar mass spectra due to...
  • Publication
    On emission-line spectra obtained from evolutionary synthesis models. II. Scale-relations and the estimation of mass dependences
    Aims: In this paper we study the influence of the ionizing cluster mass on the emission line spectrum of H ii regions in order to determine the influence of low...
  • Publication
    On surface brightness fluctuations: probabilistic and statistical bases. I. Stellar population and theoretical surface brightness fluctuations
    Aims: This work aims to provide a theoretical formulation of surface brightness fluctuations (SBF) in the framework of probabilistic population synthesis models...

    On the Extreme Positive Feedback Star-forming Mode from Massive and Compact Super Star Clusters
    The force of gravity acting within the volume occupied by young, compact, and massive super star clusters is here shown to drive in situ all the matter...
  • Publication
    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 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 origin of the compact H ii regions around massive stellar clusters
    The existence of compact H ii regions around massive stellar clusters with ages exceeding several Myr challenges our understanding of the physical processes...
