THE CHANDRA DEEP FIELD-SOUTH SURVEY: 7 MS SOURCE CATALOGS

We present X-ray source catalogs for the approximate to 7 Ms exposure of the Chandra Deep Field-South (CDF-S), which covers a total area of 484.2. arcmin(2). Utilizing WAVDETECT for initial source detection and ACIS Extract for photometric extraction and significance assessment, we create a main source catalog containing 1008 sources that are detected in up to three X-ray bands: 0.5-7.0. keV, 0.5-2.0. keV, and 2-7. keV. A supplementary source catalog is also provided,. including 47 lower-significance sources that have bright (K-s <= 23) near-infrared counterparts. We identify multiwavelength counterparts for 992 (98.4%) of the main-catalog sources, and we collect redshifts for 986 of these sources, including 653 spectroscopic redshifts and 333 photometric redshifts. Based on the X-ray and multiwavelength properties, we identify 711 active galactic nuclei (AGNs) from the main-catalog sources. Compared to the previous approximate to 4 Ms CDF-S catalogs, 291 of the main-catalog sources are new detections. We have achieved unprecedented X-ray sensitivity with average flux limits over the central approximate to 1 arcmin(2) region of approximate to 1.9. x. 10(-17), 6.4 x 10(-18), and 2.7 x 10(-17) erg cm(-2) s(-1) in the three X-ray bands, respectively. We provide cumulative number-count measurements observing, for the first time, that normal galaxies start to dominate the X-ray source population at the faintest 0.5-2.0. keV flux levels. The highest X-ray source density reaches approximate to 50,500 deg(-2), and 47% +/- 4% of these sources are AGNs (approximate to 23,900 deg(-2)).
