THE ACS FORNAX CLUSTER SURVEY. IX. THE COLOR-MAGNITUDE RELATION OF GLOBULAR CLUSTER SYSTEMS
We investigate the color–magnitude relation for globular clusters (GCs)—the so-called blue tilt—detected in the Advanced Camera for Surveys (ACS) Fornax Cluster Survey and using the combined sample of GCs from the ACS Fornax and Virgo Cluster Surveys. We find a tilt of γz ≡ d(g − z)/dz = −0.0257 ± …
