cds-question@unistra.frx-ray-sourcesinfrared-photometryastronomical-object-identificationredshiftedsurveysWe present X-ray source catalogs for the ~7Ms exposure of the Chandra Deep Field-South (CDF-S), which covers a total area of 484.2arcmin^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: 0.5-7.0keV, 0.5-2.0keV, and 2-7keV. 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 ~4Ms 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 ~1arcmin^2^ region of ~1.9x10^-17^, 6.4x10^-18^, and 2.7x10^-17^erg/cm^2^/s 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 0.5-2.0keV flux levels. The highest X-ray source density reaches ~50500deg^-2^, and 47%+/-4% of these sources are AGNs (~23900deg^-2^).2017ApJS..228....2Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/228/2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2014)III/269 : VIMOS VLT Deep Survey (VVDS) (Le Fevre+, 2013)II/261 : GOODS initial results (Giavalisco+, 2004)J/ApJ/831/145 : 6Ms Chandra long-term analyses of AGNs (Yang+, 2016)J/ApJ/825/7 : Evolution of ~6Ms CDF-S galaxies (Lehmer+, 2016)J/ApJS/224/15 : Improved 2Ms and 250ks Chandra catalogs (Xue+, 2016)J/ApJ/823/95 : CANDELS GOODS-S with Chandra counterparts (Cappelluti+, 2016)J/ApJ/819/62 : The COSMOS-Legacy Survey (CLS) catalog (Civano+, 2016)J/AJ/149/178 : Redshift cat. of galaxies in GOODS-South field (Morris+, 2015)J/A+A/576/A130 : Ultra-deep cat. of X-ray groups in ECDF-S (Finoguenov+, 2015)J/ApJ/801/97 : GOODS-S+UDS stellar masses from CANDELS (Santini+, 2015)J/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/AJ/147/52 : Structures in the Chandra Deep Field-South (Dehghan+, 2014)J/A+A/555/A42 : The XMM-CDFS catalogues (Ranalli+, 2013)J/ApJ/769/80 : Spitzer/IRAC observations of five deep fields (Ashby+, 2013)J/ApJS/205/13 : VLA 1.4GHz survey of ECDF-S (DR2) (Miller+, 2013)J/MNRAS/426/3334 : Australia Telescope Large Area Survey (Mao+, 2012)J/MNRAS/425/2116 : Arizona CDFS Environment Survey, ACES (Cooper+, 2012)J/ApJ/748/124 : AGN X-ray variability in the 4Ms catalog (Young+, 2012)J/AJ/141/64 : PEARS emission-line galaxies spectroscopy (Xia+, 2011)J/ApJ/742/3 : Photometric catalogs for ECDF-S and CDF-N (Rafferty+, 2011)J/ApJS/195/10 : The CDF-S survey: 4Ms source catalogs (Xue+, 2011)J/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/ApJS/191/124 : Opt. spectroscopy of ECDF-S X-ray sources (Silverman+, 2010)J/ApJS/187/560 : Photometric redshifts of the 2Ms CDF-S (Luo+, 2010)J/A+A/512/A12 : VLT/VIMOS spectroscopy in GOODS-South field (Balestra+, 2010)J/ApJS/183/295 : A K-selected catalog of the ECDFS from MUSYC (Taylor+, 2009)J/ApJ/693/1713 : Spectroscopy of X-ray sources in ECDF-S (Treister+, 2009)J/ApJS/179/19 : CDFS survey: 2 Ms source catalogs (Luo+, 2008)J/ApJS/174/136 : GEMS survey data and catalog (Caldwell+, 2008)J/A+A/478/83 : GOODS-South Field VLT/FORS2 redshifts.
