cds-question@unistra.frsurveysgalaxiescatalogsredshiftedWe present the Arizona CDFS Environment Survey (ACES), a recently completed spectroscopic redshift survey of the Chandra Deep Field-South (CDFS) conducted using the Inamori-Magellan Areal Camera and Spectrograph on the Magellan-Baade telescope. In total, the survey targeted 7277 unique sources down to a limiting magnitude of R_AB_=24.1, yielding 5080 secure redshifts across the ~30'x30' extended CDFS region. The ACES data set delivers a significant increase to both the spatial coverage and the sampling density of the spectroscopic observations in the field. Combined with previously published spectroscopic redshifts, ACES now creates a highly complete survey of the galaxy population at R<23, enabling the local galaxy density (or environment) on relatively small scales (~1Mpc) to be measured at z<1 in one of the most heavily studied and data-rich fields in the sky. Here, we describe the motivation, design and implementation of the survey and present a preliminary redshift and environment catalogue. In addition, we utilize the ACES spectroscopic redshift catalogue to assess the quality of photometric redshifts from both the COMBO-17 and Multiwavelength Survey by Yale-Chile imaging surveys of the CDFS.2012MNRAS.425.2116Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/425/2116CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/253 : Chandra Deep Field South: multi-colour data (Wolf+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/425/2116https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/425/2116http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/425/2116https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/425/2116https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/425/2116http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/425/2116GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/425/2116/table1 (Slitmask observation information)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/2116/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/2116/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/2116/table1?GETtext/xml+votable180.050000true53.09166667-27.890277780.005555555555555556Cone search capability for table J/MNRAS/425/2116/table2 (ACES redshift catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/2116/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/2116/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/2116/table2?GETtext/xml+votable180.050000true53.11351889-28.024921940.005555555555555556Cone search capability for table J/MNRAS/425/2116/table3 (ACES environment catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/2116/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/2116/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/2116/table3?GETtext/xml+votable180.050000true53.19700417-28.064958330.0055555555555555566/35935 359572.762881831355591e-19 3.3785437584409506e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/425/2116?format=asciiOpticaldefaultJ/MNRAS/425/2116/table1Slitmask observation informationrecnoRecord number assigned by the VizieR team.
