cds-question@unistra.frx-ray-sourcessurveysinfrared-photometryvisible-astronomyWide-band photometryultraviolet-photometryWe present the results of deep Chandra imaging of the central region of the Extended Groth Strip, the AEGIS-X Deep (AEGIS-XD) survey. When combined with previous Chandra observations of a wider area of the strip, AEGIS-X Wide (AEGIS-XW), these provide data to a nominal exposure depth of 800ks in the three central ACIS-I fields, a region of approximately 0.29deg^2^. This is currently the third deepest X-ray survey in existence; a factor ~2-3 shallower than the Chandra Deep Fields (CDFs), but over an area ~3 times greater than each CDF. We present a catalog of 937 point sources detected in the deep Chandra observations, along with identifications of our X-ray sources from deep ground-based, Spitzer, GALEX, and Hubble Space Telescope imaging. Using a likelihood ratio analysis, we associate multiband counterparts for 929/937 of our X-ray sources, with an estimated 95% reliability, making the identification completeness approximately 94% in a statistical sense. Reliable spectroscopic redshifts for 353 of our X-ray sources are available predominantly from Keck (DEEP2/3) and MMT Hectospec, so the current spectroscopic completeness is ~38%. For the remainder of the X-ray sources, we compute photometric redshifts based on multiband photometry in up to 35 bands from the UV to mid-IR. Particular attention is given to the fact that the vast majority the X-ray sources are active galactic nuclei and require hybrid templates. Our photometric redshifts have mean accuracy of {sigma}=0.04 and an outlier fraction of approximately 5%, reaching {sigma}=0.03 with less than 4% outliers in the area covered by CANDELS.2015ApJS..220...10Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/220/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/268 : DEEP2 Redshift Survey, Data Release 4 (Matthews+ 2013)V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)VII/225 : The Canada-France Redshift Survey (CFRS) (Lilly+, 1995)J/ApJ/802/89 : Luminosity function of X-ray-selected AGNs (Buchner+, 2015)J/MNRAS/443/1999 : X-ray spectral analysis of AGNs (Brightman+, 2014)J/ApJ/765/117 : X-ray group of galaxies in AEGIS (Erfanianfar+, 2013)J/MNRAS/428/3089 : X-ray properties of BzK-selected galaxies (Rangel+, 2013)J/ApJS/202/6 : XDEEP2 survey catalog (Goulding+, 2012)J/ApJS/201/30 : The Chandra COSMOS survey.
