ADC_Keywords: Clusters, galaxy ; Associations, stellar ; Radial velocities Keywords: galaxies: clusters: individual: Fornax cluster - galaxies: distances and redshifts - galaxies: individual: NGC 1399 - galaxies: kinematics and dynamics - galaxies: star clusters Abstract: We have obtained spectroscopic redshifts of colour-selected point sources in four wide area VLT-FLAMES (Very Large Telescope-Fibre Large Array Multi Element Spectrograph) fields around the Fornax cluster giant elliptical galaxy NGC 1399, identifying as cluster members 27 previously unknown faint (-10.5<Mg'←8.8) compact stellar systems (CSS), and improving redshift accuracy for 23 previously catalogued CSS. Description: Our observations over two nights in 2004 November at Cerro Paranal, Chile, were made under European Southern Observatory (ESO) observing programme 074.A-0508 with the FLAMES multifibre intermediate to high-resolution spectroscopic system attached to the Nasmyth-A focus of the 8-m Kueyen telescope.

Note (1): Type of cluster as follows: 1 = known Fornax cluster galaxies 2 = known Fornax cluster compact stellar systems (CSS) 3 = new Fornax cluster compact stellar systems (CSS) Note (2): The stellarity index (SGC-r), derived by SExtractor from r' band photometry (Karick, 2005, PhD thesis, Univ. Melbourne), compares the target light profile to a point-spread function (0 = extended object; 1 = point source) Note (3): Note on SGC-r as follows: c = Photometry of these CSS has been affected by partial blending with adjacent stars. d = UCD3 is known to have an extended stellar halo (De Propris et al. 2005ApJ...623L.105D), and may be eventually classified as a dE,N galaxy (see full version of table). e = Photometry of this CSS has been affected by blending with a background galaxy Note (4): 2dF revised velocity data are derived from Drinkwater et al. (2000PASA...17..227D) and Gregg (in preparation). Note (5): FCOS data are from the Fornax Compact Object Survey (Mieske et al., 2004, Cat. J/A+A/418/445). FCOS catalogue identifiers (as sequenced in the table): 1-017, 2-0231, 2-078, 4-2028, 2-073, 0-2025, 3-2027, 1-2053, 1-060, 3-2004, 1-2083 and 3-2019. Note (6): Bergond data are from VLT-FLAMES spectroscopy (Bergond et al., 2006, Cat. J/A+A/448/155). Note (7): Therefore, a ratio less than 1 implies they are gravitationally bound. Note (8): 'a' quotes CSS considered to be gravitationally bound to a prominent cluster galaxy other than NGC 1399 - see analysis in the text.
