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…

The Clustering of Intergalactic Metals

Christophe Pichon, Evan Scannapieco, Bastien Aracil +4

We measure the spatial clustering of metals in the intergalactic medium from z = 1.7 to 3.0, as traced by 643 CIV and 104 SiIV N >= 10^12 cm^-2 absorption systems in 19 high signal…

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…

XMM-Newton observation of the Chandra Deep Field-South: Statistical treatment of faint source spectra

A. Streblyanska, J. Bergeron, H. Brunner +3

We present first results of the X-ray spectral analysis of the 500 ksec deep survey obtained with XMM-Newton on the Chandra Deep Field South (CDFS). Statistical distributions of sp…

Metals in the Intergalactic Medium

Bastien Aracil, Patrick Petitjean, Christophe Pichon +1

We use high spectral resolution (R=45000) and high signal-to-noise ratio (S/N \~ 35-70 per pixel) spectra of 19 high-redshift (2.1<z_em<3.2) quasars to investigate the metal conten…
