SMAKCED Galaxy Decompositions (Janz et al. 2014)

SMAKCED – Stellar content, MAss and Kinematics of Cluster Early-type Dwarfs was an international collaborative project acquiring optical longslit spectra and deep near-infrared images for a large representative sample of early-type dwarf galaxies in the Virgo cluster. Two-dimensional models with inner and outer components, as well as bar and lens components, were fitted to our sample of near-infrared Virgo cluster early-type galaxy images. The resulting component parameters from Table 5 of Janz et al. 2014 are accessible through the German Astrophysical Virtual Observatory (GAVO) as well as in illustrated form with residual images and structure profiles:

SMAKCED Near-Infrared Images (Janz et al. 2012, 2014)

Deep near-infrared images were obtained for a nearly magnitude-complete sample (-19 < Mr < -16 mag) of 121 Virgo cluster early-type galaxies, as presented in Janz et al. 2012 and Janz et al. 2014. The reduced images are available through the German Astrophysical Virtual Observatory:
