Properties of QSO Metal Line Absorption Systems at High Redshifts: Nature and Evolution of the Absorbers and the Ionizing Radiation Background
Alec Boksenberg, Wallace L. W. Sargent, Michael Rauch
In Keck HIRES spectra of 9 QSOs we identify a sample of 908 CIV absorber components in 188 systems outside the Lyman forest in the redshift range 1.6 < z < 4.4, with related lines…
The Chandra Deep Field-North Survey. XV. Optically Bright, X-ray Faint Sources
A. E. Hornschemeier, F. E. Bauer, D. M. Alexander +7
We have analyzed optically bright, X-ray faint [OBXF; i.e., log(fX/fR) < -2] sources identified in an 178.9 square arcminute area within the Chandra Deep Field-North (CDF-N) 2 Ms s…
The Chandra Deep Field-North Survey. XIII. 2 Ms Point-Source Catalogs
D. M. Alexander, F. E. Bauer, W. N. Brandt +11
We present catalogs for the ~2 Ms Chandra Deep Field-North, currently the deepest X-ray observation of the Universe in the 0.5-8.0 keV band. Five hundred and three (503) X-ray sour…
