ANTICORRELATION OF VARIABILITY AMPLITUDE WITH X-RAY LUMINOSITY FOR ACTIVE GALACTIC NUCLEI

摘要

The bright-spot model for the short-term X-ray variability of active galactic nuclei predicts that, statistically, sources with larger luminosities should have smaller variability amplitudes. This quantitatively agrees with the analysis of the observational data from 12 high-quality EXOSAT long looks performed by Lawrence & Papadakis.
