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...

PublicationStar 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...

PublicationStar 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...

PublicationStatistical 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...

PublicationStellar 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...

PublicationSuper 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...

PublicationSuper 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...

PublicationSuper 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...

PublicationSupernovae 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...
