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…
The Elusive Active Nucleus of NGC 4945
A. Marconi, E. Oliva, P. P. van der Werf +4
We present new HST NICMOS observations of NGC 4945, a starburst galaxy hosting a highly obscured active nucleus that is one of the brightest extragalactic sources at 100 keV. The H…
Limits on the Spatial Extent of AGN Measured with the Fine Guidance Sensors of the HST
Richard N. Hook, Ethan J. Schreier, George Miley
The optical structure of several AGN has been studied using the Fine Guidance Sensors (FGS) on the Hubble Space Telescope (HST). The FGSs are interferometric devices which can reso…
