... Snapshot Survey for Planetary Nebulae in Local Group Globular Clusters . ... Extensive observations over the past decade, primarily with HST, have shown that massive, young star clusters are present in the nuclear regions of almost all late-type spiral galaxies. It remains unclear, however, whether those clusters harbour (or generate) the black holes that are commonly found in the central regions of both ellipticals and spiral galaxies with significant bulge components, such as our Milky Way. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
