Extraction of a deterministic component from ROSAT X-ray data using a wavelet transform and the principal component analysis. II. The data analysis.

LISZKA L., PACHOLCZYK A.G. and STOEGER W.R.

Abstract (from CDS):

A deterministic component in the X-ray photon series from Seyfert 1 galaxies and quasars, observed by ROSAT, is studied with the wavelet spectra method. A semi-regular deterministic modulation of the photon series is stronger and occurs more frequently in Seyfert 1 nuclei than in quasars indicating that by studying statistical properties of an X-ray photon train it is possible to identify unambiguously the character of its source. An interpretation of these differences is suggested within a scenario provided by a black hole nuclear cluster paradigm.
