Title of the communication: Host galaxies and cluster environment of radio-loud AGN
Preliminary abstract: We present the first results of an extensive study of the properties of the host galaxies and cluster environment of radio-loud AGN. Our sample consist of approx. 100 AGNs, including several subsamples of radio-selected BL Lac objects, QSOs and FR I and II radio galaxies taken from the 1 Jy catalogue as well as the EMSS sample of x-ray selected BL Lac objects.
