HI Signatures of Reionization
Paolo Tozzi
The exploration of the end of the Dark Ages will be one of the most exciting field of the next decade. While most of the proposed observations must await the next-generation telesc…
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…
Agns and Clusters in Chandra Deep Fields
P. Tozzi, the CDFS Team
The Chandra X-ray Satellite already observed several deep fields, including the two 1 Megasec exposures of the Chandra Deep Field South (CDFS) and North. We review here the main fi…
The Heating of the ICM: Energy Crisis and viable solutions
Paolo Tozzi
X-ray observations indicate that non-gravitational processes play a key role in the thermodynamics of the Intra Cluster Medium (ICM). The effect of non-gravitational processes is i…
The Heating of the Intra Cluster Medium
Paolo Tozzi
X-ray observations indicate that non-gravitational processes play a key role in determining the distribution of the diffuse, X-ray emitting gas in clusters of galaxies (ICM). The e…
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…
