J/AJ/137/498        UCD and bright GC in Fornax              (Gregg+, 2009)

A large population of ultra-compact dwarfs and bright intracluster globulars in the Fornax cluster. Gregg M.D., Drinkwater M.J., Evstigneeva E., Jurek R., Karick A.M., Phillipps S., Bridges T., Jones J.B., Bekki K., Couch W.J. <Astron. J., 137, 498-506 (2009)> =2009AJ....137..498G

Using the 2dF spectrograph on the Anglo-Australian Telescope, we have carried out a search for fainter UCDs in the Fornax Cluster. In the magnitude interval 19.5<bJ<21.5, we have found 54 additional compact cluster members within a projected radius of 0.9° (320kpc) of the cluster center, all of which meet our selection and observational criteria to be UCDs. Description: The original FCSS observations in the central field of the Fornax Cluster produced six UCDs in the range 16.5<bJ<20.0. Here, we define UCDs simply as objects, which were classified as "stellar" (unresolved) in the photographic Automatic Plate Measuring (APM) catalog but were found to have redshifts consistent with the membership of the Fornax Cluster (600km/s<cz<2500km/s). In 2003 October and 2004 November, we made new 2dF observations in Fornax to test this prediction. File Summary:
