X-ray power law spectra in active galactic nuclei
W. Ishibashi, T. J. -L. Courvoisier
X-ray spectra of active galactic nuclei (AGN) are usually described as power law spectra, characterized by the spectral slope or photon index . Here we discuss the X-ray spe…

X-ray variability time scales in Active Galactic Nuclei
W. Ishibashi, T. J. -L. Courvoisier
X-ray variability in Active Galactic Nuclei (AGN) is commonly analysed in terms of the Power Spectral Density (PSD). The break observed in the power spectrum can be interpreted as…
