    Simultaneous modelling of the stellar halo and globular cluster system of NGC 5128
    An important test for models of galaxy formation lies in the metallicity distribution functions (MDFs) of spheroid stars and their globular clusters (GCs). We...

    Spectroscopy of globular cluster candidates in the Sculptor group galaxies NGC 253 and 55
    We have obtained spectra for 103 published globular cluster candidates in the Sculptor group galaxies NGC 253 and 55. On the basis of radial velocities and...

    Spectroscopy of Globular Clusters in the Fornax Dwarf Galaxy
    We present low-resolution, integrated Keck spectra of the five globular clusters (GCs) of the Fornax dwarf spheroidal galaxy. We find a tentative age spread...

    Star cluster catalogues for the LEGUS dwarf galaxies
    We present the star cluster catalogues for 17 dwarf and irregular galaxies in the HST Treasury Program `Legacy ExtraGalactic UV Survey' (LEGUS). Cluster...

    Star clusters in M33
    ΛCDM-based numerical simulations predict a scenario consistent with observational evidence in Milky Way-like halos. However, less clear is the role of low-mass...

    Star formation and stellar populations across nuclear rings in galaxies
    We present a study of the optical spectra of a sample of eight star-forming nuclear rings and the nuclei of their host galaxies. The spectra were obtained with...

    Star Formation Feedback for Compact Stellar Systems
    We summarize recent theoretical results dealing with the formation of massive stellar systems. The key premise is the high stellar density which leads to a very...

    Statistical Synthesis Models
    In this contribution we evaluate the minimal cluster mass for which the effects of an incomplete sampling of the Initial Mass Function (IMF) cannot be neglected...

    Stellar Populations of Globular Clusters in the Elliptical Galaxy NGC 1407
    We present high-quality Keck spectroscopic data for a sample of 20 globular clusters (GCs) in the massive E0 galaxy NGC 1407. A subset of 20 line-strength...
