    Extragalactic globular cluster near-infrared spectroscopy: II. The stellar population synthesis model zero-point problem extends to the near-infrared
    Many recent studies have pointed out significant discrepancies between observations and models of stellar populations in the near-infrared (NIR). With current...

    Extragalactic Globular Clusters: Old Spectroscopic Ages and New Views on Their Formation
    We present the results of a meta-analysis of Keck spectra of extragalactic globular clusters (GCs) in a sample of eight galaxies, ranging from dwarf galaxies to...

    Filaments in Galactic Winds Driven by Young Stellar Clusters
    The starburst galaxy M82 shows a system of Hα-emitting filaments that extend to each side of the galactic disk. We model these filaments as the result of the...

    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...
