Analysis of Strong Outbursts in Selected Blazars from the Metsahovi and UMRAO Monitoring Databases
arXiv:astro-ph/0502171
Abstract
Frequency-dependent time lags for strong outbursts in four gamma-blazars are determined. The time lags for two adjacent outbursts in 2230+114 are correlated with the outburst amplitudes. There is evidence that bright outbursts in 2230+114 appear with a quasi-period of (8.0 +- 0.3) yr.
