    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...

    Super star clusters and their emission lines
    Super star clusters (SSCs) are young massive objects typically observed in starburst galaxies. They consist of millions of stars occupying volumes only several...

    Super star clusters in Hii galaxies
    We summarize our results based on observations with the NIRI camera on the Gemini North telescope of three Hii galaxies (Mrk 36, UM 408 and UM 461), obtained to...

    Super Star Clusters Versus OB Associations
    Super star clusters (M ecl > 105 M sun) are the largest stellar nurseries in our local Universe, containing hundreds of thousands to millions of young stars...

    Supernovae and Their Expanding Blast Waves during the Early Evolution of Galactic Globular Clusters
    Our arguments deal with the early evolution of Galactic globular clusters and show why only a few of the supernovae (SNe) products were retained within globular...

    Supersonic Line Broadening within Young and Massive Super Star Clusters
    The origin of supersonic infrared and radio recombination nebular lines often detected in young and massive superstar clusters is discussed. We suggest that...

    Testing Intermediate-Age Stellar Evolution Models with VLT Photometry of Large Magellanic Cloud Clusters. I. The Data
    This is the first of a series of three papers devoted to the calibration of a few parameters of crucial importance in the modeling of the evolution of...

    Testing Intermediate-Age Stellar Evolution Models with VLT Photometry of Large Magellanic Cloud Clusters. II. Analysis with the Yale Models
    Using Yale stellar evolution models, we present an analysis of the color-magnitude diagrams (CMDs) of three intermediate-age LMC clusters, namely, NGC 2173, SL...

    Testing Intermediate-Age Stellar Evolution Models with VLT Photometry of Large Magellanic Cloud Clusters. III. Padova Results
    The color-magnitude diagrams (CMDs) of three intermediate-age Large Megallanic Cloud clusters, NGC 2173, SL 556, and NGC 2155, are analyzed to determine their...
