More Evidence for Hidden Spiral and Bar Features in Bright Early-Type Dwarf Galaxies

Barazza, F D; Binggeli, Bruno; Jerjen, Helmut

Description

Following the discovery of spiral structure in IC 3328 (Jerjen et al. 2000), we present further evidence that a sizable fraction of bright early-type dwarfs in the Virgo cluster are genuine disk galaxies, or are hosting a disk component. Among a sample of 23 nucleated dwarf ellipticals and dSOs observed with the Very Large Telescope in B and R, we found another four systems exhibiting non-axisymmetric structures, such as a bar and/or spiral arms, indicative of a disk (IC 0783, IC 3349, NGC...[Show more]
