Photometry of Cygnus A at 800 and 1100 microns

Eales, Stephen Anthony, Alexander, P. and Duncan, W. D. 1989. Photometry of Cygnus A at 800 and 1100 microns. Monthly Notices of the Royal Astronomical Society 240 , pp. 817-822.

The fluxes of the hotspots and core of the arche-typical radio galaxy Cygnus A were measured at 800 and 1100 microns. The values for the hotspots lie on the extrapolation of the spectrum from cm-wavelengths, and are consistent with a model in which the relativistic electrons are continuously injected into a reservoir from which they escape to fill the lobes. For the central source, the data are also consistent with an extrapolation from longer wavelengths and therefore suggest that the far-infrared emission discovered by IRAS from the nucleus is from heated dust.
