Intra-night optical variability of different classes of powerful AGNAbstract. Intra-night monitoring of the optical flux has been carried out for a matched sample of 4 different classes of luminous quasars, consisting of radio-quiet and radio-loud quasars (including blazars). The campaign needed 112 nights of observations spread over 4 years. Intranight variations above 1% level were detected for all the four AGN classes, allowing their variability characteristics to be compared for the first time and to develop a possible common theoretical framework for the phenomenon.
