Abstract

It is shown that any synchrotron radiation source of sufficient compactness and containing relativistic electrons whose energy spectrum extends down to the MeV range will be able to generate observable centimeter-wavelength inverse Compton radiation provided reasonable values of source magnetic field strength are assumed, and provided also that the relativistic electron energy stored in the source exceeds certain minimum values. The model was illustrated with the aid 4C 39.25, a centimeter-excess source known to be a QSS, and the data were found not inconsistent with a cosmological interpretation of the associated redshift.It was also suggested that if the radiative power output of the model centimeter-excess radio source is not insignificant relative to the relativistic electron energy store, then temporal variations in source intensity may ensue.
