    Five young star clusters in the outer region of the Small Magellanic Cloud
    Colour-magnitude diagrams in the Washington system are presented for the first time for five star clusters projected on to the outer region of the Small...

    Formation of Star Clusters in the Large Magellanic Cloud and Small Magellanic Cloud. I. Preliminary Results on Cluster Formation from Colliding Gas Clouds
    We demonstrate that single and binary star clusters can be formed during cloud-cloud collisions triggered by the tidal interaction between the Large and Small...

    Galactic-Field Initial Mass Functions of Massive Stars
    Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) appears to be an invariant...

    Gemini/GMOS imaging of globular cluster systems in five early-type galaxies
    In this paper, we present deep high-quality photometry of globular cluster systems (GCSs) belonging to five early-type galaxies, covering a range of mass and...

    Gemini/GMOS imaging of globular clusters in the Virgo galaxy NGC 4649 (M60)
    We present Sloan g and i imaging from the Gemini Multi-object Spectrograph (GMOS) instrument on the Gemini North telescope for the globular cluster (GC) system...

    Gemini/GMOS spectra of globular clusters in the Leo group elliptical NGC 3379
    The Leo group elliptical NGC 3379 is one of the few normal elliptical galaxies close enough to make possible observations of resolved stellar populations, deep...

    Gemini/GMOS spectra of globular clusters in the Virgo giant elliptical NGC 4649
    NGC 4649 (M60) is one of a handful of giant Virgo ellipticals. We have obtained Gemini/GMOS (Gemini North Multi-Object Spectrograph) spectra for 38 globular...

    Globular Cluster and Galaxy Formation: M31, the Milky Way, and Implications for Globular Cluster Systems of Spiral Galaxies
    We find that the globular cluster (GC) systems of the Milky Way and of our neighboring spiral galaxy, M31, comprise two distinct entities, differing in three...

    Globular Cluster Metallicity Subpopulations in NGC 4472
    Bimodality is a common feature of globular cluster (GC) color distributions in galaxies. Although it is well known that the GC system of the Milky Way is...
