Abstract:Old, metal-poor globular clusters trace the formation and evolution of early-type galaxies. Their are the best probes, at low redshift, of the building-up of galaxy halos at high redshift. Their properties constrain the characteristics of their progenitors. Recent results suggest that DLAs atz > 3 are the likely hosts for their formation. Finally, they shed light on the old, metal-poor halos probably present around all early-type galaxies. This revised version was published online in September 2006 with corrections to the Cover Date.
Keywords:early-type galaxy  halo  globular cluster
