[22.01] Millimetre and Submillimetre Photometry and Imaging of Cygnus A

E. I. Robson, L. Leeuw (Joint Astronomy Centre)

We will present 2mm and 1.3mm photometry plus 850\mum through 450\mum imaging of the central nucleus and lobes in Cygnus A. Observations show that the synchrotron power law extends without break to 450\mum and with spectral indices of about 0.9 and 0.15 for the hotspots and the core, respectively. Although there is no evidence of thermal emission from dust at 450\mum, these data in combination with the IRAS do no preclude significant thermal emission from dust at 75K.
