Most quasars and Seyfert 1 galaxies have spectra that rise from optical wavelengths into the 60–100 μm infrared region, beyond which they must suffer a sharp cutoff indicated by the lack of observed millimetre emission. There is evidence1–4 that the infrared emission receives contributions from both thermal emission by interstellar dust and synchrotron… CONTINUE READING
