Testing the X-ray variability of active galactic nuclei with the non-linear prediction method
/ Abstract
The analysis of eight EXOSATX-ray light curves of six active galactic nuclei by non linear prediction methods indicates that the observed variability is truly stochastic and is not caused by deterministic chaos. This result favours X-ray emission models with multiple centres of production of hot, possibly relativistic, electrons.
