X-RAY VARIABILITY AND THE INNER REGION IN ACTIVE GALACTIC NUCLEI
X-RAY VARIABILITY AND THE INNER REGION IN ACTIVE GALACTIC NUCLEI
We present theoretical models of X-ray variability attributable to orbital signatures from an accretion disk including emission region size, quasi-periodic oscillations (QPOs), and its quality factor Q, and the emergence of a break frequency in the power spectral density shape. We find a fractional variability amplitude of . We conduct …
