X-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 کاملHeavy X-ray Absorption in Soft X-ray Weak Active Galactic Nuclei
Recent ROSAT studies have identified a significant population of Active Galactic Nuclei (AGN) that are notably faint in soft X-rays relative to their optical fluxes. Are these AGN intrinsically X-ray weak or are they just highly absorbed? Brandt, Laor & Wills have systematically examined the optical and UV spectral properties of a well-defined sample of these soft X-ray weak (SXW) AGN drawn fro...
متن کاملIonized Ultraviolet and Soft-X-ray Absorption in the Low Redshift Active Galactic Nucleus PG1126−041
We present here the analysis of ultraviolet spectra from IUE and an X-ray spectrum from ROSAT PSPC observations of the X-ray weak, far-infrared loud AGN, PG 1126−041 (Mrk 1298). The first UV spectra taken in June 1992, simultaneously with ROSAT, show strong absorption lines of NV, CIV and SiIV, extending over a velocity range from −1000 to −5000 km s with respect to the corresponding line centr...
متن کاملAccretion Flows in X–Ray Binaries and Active Galactic Nuclei
Hard X–ray emission is ubiquitous in accreting black holes, both in Galactic binary systems and in Active Galactic Nuclei. I review the different spectra which can be seen from these systems, and possible ways of producing this emission. X–ray reflection should give an observational test of these scenarios, but we need better models before this can give an unambiguous diagnostic of the accretio...
متن کاملActive Galactic Nuclei and the Cosmic X-Ray Background
Active Galactic Nuclei (AGNs) are the most luminous objects in the Universe (besides Gamma-Ray Bursts). Typical spatial scales for these objects are estimated from time variability, giving sizes of around one parsec (Clavel al. 1991, Peterson et al. 1992), similar to our solar system, but with typical luminosities 1011 larger than the Sun. It is believed that their energy comes from the inflow ...
