The recent X-ray history of NGC 5506

Astrophysics 2008-11-26 v1

Abstract

We present a detailed discussion of the spectral and spatial components of NGC 5506, based on XMM-Newton, Chandra and BeppoSAX observations. The overall picture consists of a nucleus absorbed by cold gas with column density of 1022\approx10^{22} cm2^{-2} and surrounded by a Compton-thick torus, whose existence is inferred by a cold reflection component and an iron Kα\alpha line. On a much larger scale, a photoionized gas extended on 350\approx350 pc reprocesses the nuclear radiation, producing a soft excess and ionized iron lines. Noteworthy, we find no evidence for the presence of the accretion disc.
