J/A+A/383/823       Radial velocities of UCOs in Fornax      (Mieske+, 2002)

Ultra compact objects in the Fornax cluster of galaxies: Globular clusters or dwarf galaxies? Mieske S., Hilker M., Infante L. <Astron. Astrophys. 383, 823 (2002)> =2002A&A...383..823M
ADC_Keywords: Clusters, galaxy ; Galaxies, optical ; Redshifts ; Photometry Keywords: galaxies: clusters: individual: Fornax cluster - galaxies: dwarf - galaxies: fundamental parameters - galaxies: luminosity function Description: The relation between the Ultra Compact Objects (hereafter UCOs) recently discovered in the Fornax cluster (Drinkwater et al., 2000PASA...17..227D; Hilker et al., 1999, Cat. J/A+AS/134/75) and the brightest globular clusters associated with the central galaxy NGC 1399 has been investigated. A spectroscopic survey on compact objects in the central region of the Fornax cluster was carried out with the 2.5 m du Pont telescope (LCO) at Las Campanas, in the three nights of 2000/12/30 to 2001/01/01. The magnitude limit was approx. V=21 mag, the spectral resolution approx. 4Å. UCOs and the bright NGC 1399 globular clusters with similar brightness were inspected. 12 GCs from the bright end of the globular cluster luminosity function have been identified as Fornax members. Eight are new members, four were known as members from before. File Summary:

Note (1): *: The object's radial velocity could be determined only by identification of emission lines, because cross correlation yielded unreliable results. Note (2): The photometry is from Hilker et al. (2002, in prep.)
