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 X-Ray Luminosity Function of Active Galactic Nuclei
M. Schmidt, R. Giacconi, G. Hasinger +2
We derive an X-ray luminosity function for active galactic nuclei (AGN) that accounts for the X-ray source counts in the 0.5-2.0 and 2-10 keV energy ranges, the redshift distributi…
The ROSAT Deep Surveys
G. Hasinger, I. Lehmann, R. Giacconi +3
The ROSAT Deep Survey in the Lockman Hole is the most sensitive X-ray survey performed to date, encompassing an exposure time of 200 ksec with the PSPC and 1.2 Msec with the HRI. T…
The ROSAT Deep Survey IV. A distant lensing cluster of galaxies with a bright arc
G. Hasinger, R. Giacconi, J. E. Gunn +7
An unusual double-lobed extended X-ray source (RX J105343+5735) is detected in the ROSAT ultra-deep HRI image of the Lockman Hole. The angular size of the source is 1.7 X 0.7 arcmi…
The ROSAT Deep Survey II. Optical identification, photomettry and spectra of sources in the Lockman field
Maarten Schmidt, Guenther Hasinger, James Gunn +7
The ROSAT Deep Survey includes a complete sample of 50 X-ray sources with fluxes in the keV band larger than 5.5 erg cm s in the Lockman field (H…
