Beginning of ReadMe : J/A+A/463/503 Early-type dwarf galaxies in Fornax cluster (Mieske+, 2007) ================================================================================ The early-type dwarf galaxy population in the Fornax cluster. Mieske S., Hilker M., Infante L., Mendes de Oliveira C. <Astron. Astrophys. 463, 503 (2007)> =2007A&A...463..503M ================================================================================ ADC_Keywords: Galaxies, photometry ; Photometry, CCD ; Photometry, surface Keywords: galaxies: clusters: individual: Fornax cluster - galaxies: dwarf - galaxies: fundamental parameters - techniques: photometric - galaxies: luminosity function, mass function Abstract: We analyse the photometric properties of the early-type Fornax cluster dwarf galaxy population, based on a wide field imaging study of the central cluster area in V and I. We used the instrument/telescope combination IMACS/Magellan at Las Campanas Observatory. We create a fiducial sample of Fornax cluster dwarf ellipticals (dEs) in the following three steps: (1) To verify cluster membership, we measured I-band surface brightness fluctuation (SBF) distances to candidate dEs; (2) We re-assessed morphological classifications for candidate dEs too faint for SBF detection; and (3) We searched for new candidate dEs in the size-luminosity regime close to the resolution limit of previous surveys. (1) We confirm cluster membership for 28 candidate dEs in the range -16.6<M_V_<-10.1mag by means of SBF distances. We find no SBF background galaxy. (2) Of 51 further candidate dEs in the range -13.2<M_V_<-8.6mag, 2/3 are confirmed as probable cluster members by morphological re-assessment, while 1/3 are re-classified as probable background objects. (3) We find 12 new dE candidates in the range -12.3<M_V_<-8.8mag. The surface brightness-magnitude relation defined by the resulting fiducial dE sample shows that Fornax dEs are about 40% larger than Local Group dEs. The Fornax dE sample furthermore defines a colour-magnitude relation that appears slightly shallower than that of Local Group dEs. The early-type dwarf galaxy luminosity function in Fornax has a faint end slope alpha=-1.1+/- 0.1. Description: Total V-band magnitude, central V-band surface brightness, and V-I colour is presented for a sample of 100 dwarf elliptical galaxy candidates in the central Fornax cluster. We also give the cluster membership flag assigned to each galaxy, based upon distance measurements obtained with the SBF method and on morphological assessment. For most of the sources, the photometric parameters are derived from imaging with the IMACS instrument at the Magellan telescope on Las Campanas Observatory. For some fainter sources the photometric parameters were derived from imaging with the WFCCD camera at the 2.5m du Pont telescope on Las Campanas Observatory. Those sources are specifically indicated in the comments column of the table.
