" A Unified Picture of the Lifecycles of Star Cluster "

Michael Fall

(STScI)


We present a unified picture of the lifecycles of star clusters, beginning with their formation in dense molecular clouds in the interstellar medium and ending with their dissolution in the the general field-star population. This picture was developed through a combination of detailed observations of clusters systems, particularly those in the Solar neighborhood and in the interacting Antennae galaxies, along with several theoretical studies, in collaboration with Rupali Chandar, Brad Whitmore, and Qing Zhang. This picture turns out to be remarkably simple, although undoubtedly approximate. By a few simple formulae, it accounts for most, if not all, the main statistical properties of star cluster systems (formation rates, mass functions, age distributions, etc). These formulae embody and clarify the physical processes involved in the formation and evolution of cluster systems, although there are still a few unresolved theoretical issues.
If there is interest by the audience, we can also present briefly some results on the possible detection of reionization sources in the Hubble Ultra-Deep Field.


Seminars are also held at JAC, CFHT, and IfA.
