" A Unified Picture of the Lifecycles of Star Cluster "
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,
