Metal-rich and metal-poor globular clusters in ellipticals: Did we learn anything? or Constraints on galaxy formation and evolution from globular cluster sub-populations | | Markus Kissler-Patig
; | | Date: |
22 May 2001 | | Subject: | astro-ph | | Affiliation: | European Southern Observatory,Germany | | Abstract: | A brief review on globular cluster sub-populations in galaxies, and their constraints on galaxy formation and evolution is given. The metal-poor and metal-rich sub-populations are put in a historical context, and their properties, as known to date, are summarized. We review why the study of these sub-populations is extremely useful for the study of galaxy formation and evolution, but highlight a few caveats with the current interpretations. We re-visit the current globular cluster system formation scenarios and show how they boil down to a single scenario for the metal-poor clusters (namely the formation in ``universal’’, small fragments at high $z$) and that a hierarchical formation seems favored for the metal-rich clusters. | | Source: | arXiv, astro-ph/0105379 | | Services: | Forum | Review | PDF | Favorites | |
