Faint dwarf spheroidals in the Fornax Cluster. A flat luminosity function.


Abstract (from CDS):

We have discovered ≃70 very faint dwarf galaxies in the Fornax Cluster. These dSphs candidates follow the same magnitude-surface brightness relation as their counterparts in the Local Group, and even extend it to fainter limits. The faintest dSph candidate in our sample has an absolute magnitude of MV≃-8.8mag and a central surface brightness of µV≃27mag/arcsec2. There exists a tight color-magnitude relation for the early-type galaxies in Fornax that extends from the giant to the dwarf regime. The faint-end slope of the luminosity function of the early-type dwarfs is flat (α≃-1.1±0.1), contrary to the results obtained by Kambas et al. (2000AJ....120.1316K).
