The hard X-ray view of bright infrared galaxies
Aims. The synthesis of the cosmic X-ray background (CXB) requires a large population of Compton-thick active galactic nuclei that have not been detected so far. We probe whether bright infrared galaxies could harbor a population of Compton-thick nuclei and if they could contribute significantly. Methods. We analyzed 112 Msec of INTEGRAL observations obtained on 613 galaxies from the IRAS Revise...
متن کاملAGN Zoo and Classications of Active Galaxies
We review the variety of Active Galactic Nuclei (AGN) classes (so-calledAGN zoo") and classification schemes of galaxies by activity types based on their optical emission-line spectrum, as well as other parameters and other than optical wave-length ranges. A historical overview of discoveries of various types of active galaxies is given, including Seyfert galaxies, radio galaxies, QSOs, BL Lace...
متن کاملX-ray spectrum as seen by BeppoSAX
The BeppoSAX archive is currently the largest reservoir of high sensitivity simultaneous soft and hard-X ray data of Seyfert galaxies. From this database all the Seyfert galaxies (105 objects of which 43 are type I and 62 are type II) with redshift lower than 0.1 have been selected and analyzed in a homogeneous way (Dadina 2007). Taking advantage of the broad-band coverage of the BeppoSAX MECS ...
متن کاملHARD X–RAY EMISSION FROM EXTRAGALACTIC IRAS 12μm SOURCES: CONSTRAINTS ON THE UNIFIED AGN MODEL AND THE SYNTHESIS OF THE X-RAY BACKGROUND XAVIER BARCONS
We analyze the 2−10 keV X-ray emission of complete samples of AGN and galaxies selected at 12μm and recently compiled by Rush, Malkan & Spinoglio (1993). The content in active galaxies of the 12μm sample is indeed much larger and less biased against low luminosity and ‘hidden’ active nuclei than for samples selected at other wavelengths. As a necessary complement we also study the IR emissivity...
متن کاملIsotropic Luminosity Indicators in a Complete Agn Sample
The [O IV] λ25.89 μm line has been shown to be an accurate indicator of active galactic nucleus (AGN) intrinsic luminosity in that it correlates well with hard (10–200 keV) X-ray emission. We present measurements of [O IV] for 89 Seyfert galaxies from the unbiased revised Shapley–Ames (RSA) sample. The [O IV] luminosity distributions of obscured and unobscured Seyferts are indistinguishable, in...
