Most hard X-ray selected quasars in Chandra Deep Fields are obscured
J. X. Wang, P. Jiang, Z. Y. Zheng +13
Measuring the population of obscured quasars is one of the key issues to understand the evolution of active galactic nuclei (AGNs). With a redshift completeness of 99%, the X-ray s…
Relativistic outflow in CXO CDFS J033260.0-274748
J. X. Wang, T. G. Wang, P. Tozzi +10
In this letter we report the detection of a strong and extremely blueshifted X-ray absorption feature in the 1 Ms Chandra spectrum of CXO CDFS J033260.0-274748, a quasar at z = 2.5…
The spatial clustering of X-ray selected AGN and galaxies in the Chandra Deep Field South and North
R. Gilli, E. Daddi, G. Zamorani +10
We investigate the spatial clustering of X-ray selected sources in the two deepest X-ray fields to date, namely the 2Msec Chandra Deep Field North (CDFN) and the 1Msec Chandra Deep…
Prevalence of X-ray variability in the Chandra Deep Field South
M. Paolillo, E. J. Schreier, R. Giacconi +2
We studied the X-ray variability of sources detected in the Chandra Deep Field South (Giacconi et al. 2002), nearly all of which are low to moderate z AGN (Tozzi et al. 2001). We f…
The Chandra Deep Field South: Optical Spectroscopy I
G. P. Szokoly, J. Bergeron, G. Hasinger +15
We present the results of our spectroscopic follow-up program of the X-ray sources detected in the 942 ks exposure of the Chandra Deep Field South (CDFS). 288 possible counterparts…
Hubble Space Telescope Imaging in the Chandra Deep Field South: III. Quantitative Morphology of the 1Ms Chandra Counterparts and Comparison with the Field Population
N. A. Grogin, A. M. Koekemoer, E. J. Schreier +8
We present quantitative morphological analyses of 37 HST/WFPC2 counterparts of X-ray sources in the 1 Ms Chandra Deep Field-South (CDFS). We investigate: 1) 1-D surface brightness…
