文摘

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.
