Abstract
The aim of this study is to establish the frequency of nuclear activity (AGN and star formation) in galaxies belonging to Compact Groups (CGs) and to characterize the type of activity as a function of the properties of both host galaxies and their parent group. To do so, we have selected a statistically complete sample of 65 groups from the Hickson's Catalogue of CGs and obtained medium resolution spectroscopy for 200 galaxies, from which 167 have been now reduced and analyzed. Adding 71 galaxies previously observed by Coziol et al. (1998, 2000, 2004) we obtain a sample of 238 galaxies. Of these, 153 (64%) show emissions and 76% possibly host an AGN.
