Far-infrared/millimetre emission in 3C sources. Dust in radio galaxies and quasars.

ANDREANI P., FOSBURY R.A.E., VAN BEMMEL I. and FREUDLING W.

Abstract (from CDS):

We present far-infrared and millimetric observations of a sample of 3C objects. Millimetre data were taken at 1.25mm with the IRAM 30m antenna feeding the MPIfR bolometer array. Mid-infrared (MIR) and far-infrared (FIR) photometry were carried out with the ISOCAM and ISOPHOT cameras on the ISO Satellite. Additional FIR IRAS observations are also included. We present the entire Spectral Energy Distributions (SEDs) from the UV to radio and discuss the emitting mechanisms. Two composite spectra, one for the radio galaxies and one for the radio quasars, are built in the object rest frame. While the SEDs of the two classes differ, they are indistinguishable in the MIR and FIR range where they probably arise as thermal emission from a dusty torus and a larger-scale (cooler) dust distribution in the host galaxy.
