The space density of Compton-thick AGN at z~0.8 in the zCOSMOS-Bright Survey
C. Vignali, M. Mignoli, R. Gilli +5
The obscured accretion phase in BH growth is a key ingredient in many models linking the AGN activity with the evolution of their host galaxy. At present, a complete census of obsc…

On the nature of the absorber in IRAS 09104+4109: the X-ray and mid-infrared view
C. Vignali, E. Piconcelli, G. Lanzuisi +8
We present a long (~76 ks) Chandra observation of IRAS 09104+4109, a hyper-luminous galaxy, optically classified as a Type 2 AGN hosted in a cD galaxy in a cluster at z=0.442. We a…
