Astrophysical: Star clusters

  • Publication
    Constraining nuclear star cluster formation using MUSE-AO observations of the early-type galaxy FCC 47
    Context. Nuclear star clusters (NSCs) are found in at least 70% of all galaxies, but their formation path is still unclear. In the most common scenarios, NSCs...

    Constraining the stellar populations of ultra-diffuse galaxies in the MATLAS survey using spectral energy distribution fitting
    We use spectral energy distribution fitting to place constraints on the stellar populations of 59 ultra-diffuse galaxies (UDGs) in the low-to-moderate density...
  • Publication
    Constraining the top-light initial mass function in the extended ultraviolet disk of M 83
    Context. The universality or non-universality of the initial mass function (IMF) has significant implications for determining star formation rates and star...

    Constraints to the masses of brown dwarf candidates form the lithium test
    We present intermediate dispersion (0.7-2.2 A/pixel) optical spectroscopic observations aimed at applying the 'lithium test' to a sample of 10 brown dwarf...
  • Publication
    Deep CCD photometry of stars in the globular cluster M3
    CCD photometry of faint stars in the globular cluster M3 is presented. The observations reach down to V equal to about 23 mag, with a sample of approximately...
  • Publication
    Density waves and star formation in grand-design spirals
    Context. H II regions in the arms of spiral galaxies are indicators of recent star-forming processes. They may have been caused by the passage of the density...
  • Publication
    Detailed chemical composition of the globular cluster Sextans A GC-1 on the outskirts of the Local Group
    Context. The chemical composition of globular clusters (GCs) across the Local Group provides information on chemical abundance trends. Studying GCs in isolated...
  • Publication
    Detection and measurement of expanding ionized shells around young star clusters
    We present a new method (BUBBLY) for detecting expanding components of ionized gas using integral field spectroscopy, showing its capabilities not only in...
  • Publication
    Diversity of nuclear star cluster formation mechanisms revealed by their star formation histories
    Nuclear star clusters (NSCs) are the densest stellar systems in the Universe and are found in the centres of all types of galaxies. They are thought to form via...
