The Role of Interstellar Scintillation in Intraday Variations at Centimetre Wavelengths
Abstract
The evidence in support of interstellar scintillation as the predominant cause of intraday variations at centimetre wavelengths is reviewed. A new evaluation of the highest brightness temperature implied for AGN is found to be consistent with the Doppler factors in typical jet models, but requires the scattering to occur within about 30pc of the Earth.
