Abstract (from CDS):

We present the results of a search for ultracompact dwarf galaxies (UCDs) in six different galaxy groups: Dorado, NGC1400, 0681, 4038, 4697 and 5084. We searched in the apparent magnitude range 17.5 ≤ bJ ≤ 20.5 (except NGC5084: 19.2 ≤ bJ≤ 21.0). We found one definite plus two possible UCD candidates in the Dorado group and two possible UCD candidates in the NGC1400 group. No UCDs were found in the other groups. We compared these results with predicted luminosities of UCDs in the groups according to the hypothesis that UCDs are globular clusters formed in galaxies. The theoretical predictions broadly agree with the observational results, but deeper surveys are needed to fully test the predictions.
