24 micron Properties of X-ray Selected AGN
J. R. Rigby, G. H. Rieke, R. Maiolino +13
We examine the 24 micron to X-ray color of 157 X-ray--selected AGN as a function of X-ray obscuration and optical classification in the Chandra Deep Field South. The sample consist…
Detections of Warm-Hot Intergalactic Medium
L. Zappacosta, R. Maiolino, F. Mannucci +3
Several popular cosmological models predict that most of the baryonic mass in the local universe is located in filamentary and sheet-like structures associated with groups and clus…
Chandra Deep Field South: The 1Msec Catalog
R. Giacconi, A. Zirm, J. Wang +15
In this Paper we present the source catalog obtained from a 942 ks exposure of the Chandra Deep Field South (CDFS), using ACIS-I on the Chandra X-ray Observatory. Catalog generatio…
HST Imaging in the Chandra Deep Field South: I. Multiple AGN Populations
E. J. Schreier, A. M. Koekemoer, N. A. Grogin +9
We present preliminary results from imaging three HST/WFPC2 fields in V and I within the Chandra Deep Field South (CDFS). HST's sensitivity and resolution are sufficient to reveal…
Testing the AGN models for the X-ray background
R. Gilli
We will briefly examine the following three issues related to the AGN synthesis models for X-ray background: 1) the possibility that absorbed AGNs evolve faster than unabsorbed one…
Sub-mm and X-ray background: two unrelated phenomena?
P. Severgnini, R. Maiolino, M. Salvati +9
Obscured AGNs are thought to contribute a large fraction of the hard X-ray background (2-10 keV), and have also been proposed as the powerhouse of a fraction of the SCUBA sources w…
