VLT Surface Photometry and Isophotal Analysis of Early-type Dwarf Galaxies in the Virgo Cluster

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

Description

We have carried out surface photometry and an isophotal analysis for a sample of 25 early-type dwarf (dE and dS0) galaxies in the Virgo cluster based on CCD images taken at the VLT with FORS1 and FORS2. For each galaxy we present B and R-band surface brightness profiles, as well as the radial colour (B - R) profile. We give total apparent BR magnitudes, effective radii, effective surface brightnesses and total colour indices. The light profiles have been fitted with Sérsic models and the...[Show more]
