Compton-thick AGN inside local ULIRGs
Abstract
We present an X-ray analysis of luminous obscured active galactic nuclei (AGN) inside local ultraluminous infrared galaxies (ULIRGs), based on Chandra, XMM-Newton and Suzaku observations. Most AGN in our sample are unidentified in the optical, and even in the hard Xrays only reflection signatures (if any) are detected. This implies that the circumnuclear environs in these composite ULIRGs are much richer in gas/dust than in ordinary active galaxies, as confirmed by the conclusive detection of the Compton-thick core of IRAS 12071-0444 thanks to Suzaku/PIN.
