Scientific paper

Wavelet analysis is applied to the microvariability light curves ofblazars 0716+714, ON231 and BL Lac. We analyzed 13microvariability light curves and determined the two most powerfulperiods for each data set using the IDL wavelet toolkit. Periodswere compared between data sets to identify trends. Relativisticcosmological and beaming effects were used to determine the periods inthe rest frame of the objects. These periods were then used to drawconclusions about the physical conditions in the relativisticjet. We interpret the flux variations in terms of collectiveplasma processes in the jets. From our analysis, inhomogeneitiesin the ambient jet medium are a length scales of 10(13) meters.
