X-ray timing studies of Active Galactic Nuclei

摘要：

We present a power spectral analysis survey of 24 active galactic nuclei (AGN). We combine x-ray observations to produce a power spectrum covering a broad range of Fourier frequencies and fit the power spectrum of each AGN using a single-bend power-law model. Using the resultant bend time-scales of 18 AGN, and of the Galactic black hole X-ray binaries Cyg X-1 and GRS1915+105, We present a plot of observed bend time-scales versus the predicted bend time-scales determined from published masses and bolometric luminosities. The results confirm our previously proposed scaling relation of bend time- scale with mass divided by accretion rate. All work
