Short time-scale X-ray variability of Active Galactic Nuclei
Abstract
In this work we have investigated short time-scale variability of NGC 4051 and NGC 4388. The quasi-steady QPO's time scale of 392017 sec was detected for NGC 4051. For the case of NGC 4388 we investigated rapid variability of the parameters of spectral models. To obtain these results, a new "Moving Fit" method for processing of the trailed X-ray spectrograms was developed.
