X-ray variability time scales in Active Galactic Nuclei
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 a characteristic X-ray variability time scale. Here we study variability properties within the framework of clumpy accretion flows, in which shocks between accreting elements account for the UV and X-ray emissions. We...
متن کاملLow-mass Active Galactic Nuclei with Rapid X-ray Variability
We present a detailed study of the optical spectroscopic properties of 12 active galactic nuclei (AGNs) with candidate low-mass black holes (BHs) selected by Kamizasa et al. through rapid X-ray variability. The highquality, echellette Magellan spectra reveal broad Hα emission in all the sources, allowing us to estimate robust viral BH masses and Eddington ratios for this unique sample. We confi...
متن کاملX-ray absorption in Active Galactic Nuclei
We review some of the main physical and statistical properties of the X-ray absorber in AGNs. In particular, we review the distribution of the absorbing column density inferred from X-ray observations of various AGN samples. We discuss the location of the X-ray absorber and the relation with the dust absorption at optical and infrared wavelengths. Finally, we shortly review the recent findings ...
متن کاملVariability of Active Galactic Nuclei
Continuum and emission-line variability of active galactic nuclei provides a powerful probe of microarcsecond scale structures in the central regions of these sources. In this contribution, we review basic concepts and methodologies used in analyzing AGN variability. We develop from first principles the basics of reverberation mapping, and pay special attention to emission-line transfer functio...
متن کاملThe X-Ray Luminosity Function of Active Galactic Nuclei
We derive an X-ray luminosity function for active galactic nuclei (AGN) that accounts for the X-ray source counts in the 0.5–2.0 and 2–10 keV energy ranges, the redshift distribution of AGNs in the ROSAT Deep Survey (RDS), as well as the X-ray background (XRB) from 1–10 keV. We emphasize the role of X-ray absorption, which has a large effect on the faint end of the 2– 10 keV source counts, as w...
