2000A&A...359..523V ISOPHOT observations of 3CR quasars and radio galaxies. VAN BEMMEL I.M., BARTHEL P.D., DE GRAAUW T. Received 23 June 1999/Accepted 26 April 2000 Abstract: In order to check for consistency with the radio-loud AGN unification scheme, ISOPHOT data obtained for two small sets of intermediate redshift steep-spectrum 3CR radio galaxies and quasars are being examined. Supplementary submillimeter and centimeter radio data for the quasars are also taken into account, in order to assess the magnitude of any beamed nonthermal radiation. The fact that we find broad-lined objects to be somewhat more luminous in their far-infrared output than narrow-lined objects, hints at a contradiction to the unification scheme. However, as the sample objects are not particularly well matched, the sample size is small, and the FIR radiation may still be partly anisotropic, this evidence is, at the moment, weak. Key words: galaxies: active - galaxies: quasars: general - infrared: general
