Samenvatting

Powerful radio-loud AGN, by virtue of their optically-thin low-frequency radio emission, represent unique targets in orientation-based unification studies, and in searches for orientation indicators and orientation invariants. Central in these efforts is the landmark Third Cambridge Catalog of Radio Sources (3CR), a sample which has been observed with most ground- and space-based telescopes over much of the electromagnetic spectrum. Using mainly Herschel and Spitzer photometric data, we recently studied the full infrared spectral energy distributions of the complete sample of 3CR radio sources at redshifts z>1. We found that the radio-loud quasars (QSRs, Type 1) and the radio galaxies (RGs, Type 2) have completely different mid-infrared, but remarkably similar far-infrared colors. These findings are in line with the view that powerful QSRs and RGs belong to the same parent population and support previously reported findings in other wavelength domains.
