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 Extended Chandra Deep Field-South Survey. Chandra Point-Source Catalogs
B. D. Lehmer, W. N. Brandt, D. M. Alexander +17
We present Chandra point-source catalogs for the Extended Chandra Deep Field-South (E-CDF-S) survey. The E-CDF-S consists of four contiguous 250 ks Chandra observations covering an…
Optimal slit orientation for long multi-object spectroscopic exposures
G. P. Szokoly
Historically, long-slit spectroscopic observations were carried out using the parallactic angle for the slit orientation if slit loss was an important consideration (either to maxi…
The Chandra Deep Field South/GOODS survey. Optically faint X-ray sources
V. Mainieri, P. Rosati, P. Tozzi +11
We provide important new constraints on the nature and redshift distribution of optically faint (R>25) X-ray sources in the Chandra Deep Field South Survey. We show that we can der…
The Galaxy Populations of Double Cluster RX J1053.7+5735 at z=1.13
Yasuhiro Hashimoto, J. Patrick Henry, Guenther Hasinger +3
We present a study of the galaxy population in the cluster RX J1053.7+5735, one of the most distant X-ray selected clusters of galaxies, which also shows an unusual double-lobed X-…
Active Galactic Nuclei in the Sloan Digital Sky Survey: I. Sample Selection
Lei Hao, Michael A. Strauss, Christy A. Tremonti +18
We have compiled a large sample of low-redshift active galactic nuclei (AGN) identified via their emission line characteristics from the spectroscopic data of the Sloan Digital Sky…
