摘要
We discuss the multi-wavelength properties of the radio galaxies 3C 31, 3C 264, 3C 270, 3C 465 and NGC 7052. The data have been deduced from observations with the VLBI/VLA arrays, HST and ROSAT. The SED of these sources, when compared with that of BL Lacs shows that beaming effects are important, but are not enough-in the simplest scenario-to explain the different properties of these two classes of objects. No relevant obscuration from inner tori seems to occur. (C) 2002 Published by Elsevier Science B.V.
