Restarting engine in an X-shaped radio galaxy
Lakshmi Saripalli, Ravi Subrahmanyan, Tanmoy Laskar +1
J2018-556, an X-shaped FR-I radio galaxy provides a unique opportunity to discuss the formation scenarios for the extended structures seen in this class of radio sources. An unders…
The UDF05 Follow-up of the HUDF: I. The Faint-End Slope of the Lyman-Break Galaxy Population at z~5
P. A. Oesch, M. Stiavelli, C. M. Carollo +14
We present the UDF05 project, a HST Large Program of deep ACS (F606W, F775W, F850LP) and NICMOS (F110W, F160W) imaging of three fields, two of which coincide with the NICP1-4 NICMO…
Infrared Number Counts of AGN in the GOODS Fields
E. Treister, C. Megan Urry, the GOODS AGN Team
Using the known numbers and evolution of unobscured AGN, and assuming that there is a large number of corresponding obscured AGN -- as expected if AGN unification is correct -- we…
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…
