Presentation Transcript

1. The Globular Cluster-Galaxy Connection1st meeting: July 1992;Globular Clusters Within the Context of Their Parent Galaxies2nd meeting: July 2011;KraftFest 20113rd meeting: July 2030 (subtitle to be decided at a later date)

2. GCGC-I conference photo

3. GCGC-I conference photo attendees at both workshops

4. GCGC-1 Major Topics The properties of the Galactic globular cluster system The stellar content of Galactic globular clusters Relationship between Globulars and other Galactic populations The globular cluster systems of the Magellanic Clouds The globular cluster populations of M31 and M33 Extragalactic globular cluster systems Observational examples of analogs to proto-globular clusters Space-based observations of globular clusters Theories for the formation and evolution of globular clusters The formation and evolution of globular cluster systems within the context of their parent galaxies

5. Some differences this time: a personal viewbigger and better observational/computational facilitiesKeck HIRES, Lick Hamilton, Magellan MIKE, VLT UVES, …Keck DEIMOS, VLT GIRAFFE & FLAMES, …dwarf spheroidal data in bulkmultiple globular populations now a realityn-body simulations are now N-BODYage differences maybe not as key an issue now?now RR Lyr and other HB stars studied in detaildetailed interior modeling of late stellar evolutionmore realistic “origin” attacks with chemical evolution

6. GCGC-1 Questionable Quotes Community standards regarding appropriate behavior of globular clusters has changed We did that measurement, but don’t believe it You have to dissect the Horizontal Branch into the horizontal part, and not-so-horizontal part, and the nearly vertical part CNO? Just say NO! I see that you are not convinced, but you can believe me for the moment The dSph galaxies do not photograph well There’s scarcely any object in the universe which hasn’t been nominated as a site of globular cluster formationASP Conference Series, 1992, vol 48, ed.
