... 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. ...

... Dr. Stella Kafka . Thursday, Dec 10, 2015 at 8:00 PM . Type I Supernovae are massive stellar explosions that result from an interaction between a white dwarf and a companion whose mass it accrues in a close binary system. When the white dwarf’s mass reaches 1.4 that of the sun, the supernova occurs. ...

The merging galaxy Arp 220 is the prototypical luminous infrared galaxy. ... In 1996, one of the then largest VLBI experiments was conducted on Arp 220, using the compact OH maser peak as a convenient phase reference. This permitted continuum imaging of the galaxy with high sensitivity, revealing the existence of roughly a dozen unresolved sub-mJy point sources scattered across the nuclear region of the galaxy. ...
