Beamed radio and far infrared emission in quasars and radio galaxies.
Abstract
Simple orientation model predictions for the radio to far infrared spectral energy distributions of radio-loud AGN are confronted with observations at various radio frequencies. This model is subsequently used to investigate 60μm far-infrared data. The results are supportive of the unified scheme for Fanaroff-Riley class II radio galaxies and quasars. The relative strength of the beamed component is derived as a function of frequency, and it is found that the higher far infrared fluxes of quasars, as compared to radio galaxies, can be explained invoking moderately beamed nonthermal far-infrared emission.
