The connection between AGN and their host galaxies has been widely studiedover recent years, showing it to be of great importance for providing answersto some fundamental questions related with AGN fueling mechanisms, theirformation and evolution. Using X-ray and one of the deepest broad-band opticaldata sets, we studied morphology and colours in relationship with X-rayproperties for sources at redshifts z < 2.0, using a sample of 262 AGN in theSubaru/XMM-Newton Deep Survey (SXDS). Morphological classification was obtainedusing the galSVM code, one of the new methods useful especially when dealingwith high-redshift sources and low-resolution data. Colour-magnitude diagramswere studied in relationship with redshift, morphology, X-ray obscuration, andX-ray-to-optical flux ratio. Finally, the significance of different regions wasanalysed on colour-magnitude diagrams, relating the observed properties of AGNpopulations with some models of their formation and evolution.
