cds-question@unistra.frgalaxy-clustersredshiftedgalaxy-kinematicsWe present a comprehensive structure detection analysis of the 0.3deg^2^ area of the MUSYC-ACES field, which covers the Chandra Deep Field-South (CDFS). Using a density-based clustering algorithm on the MUSYC and ACES photometric and spectroscopic catalogs, we find 62 overdense regions up to redshifts of 1, including clusters, groups, and filaments. We also present the detection of a relatively small void of ~10Mpc^2^ at z~0.53. All structures are confirmed using the DBSCAN method, including the detection of nine structures previously reported in the literature. We present a catalog of all structures present, including their central position, mean redshift, velocity dispersions, and classification based on their morphological and spectroscopic distributions. In particular, we find 13 galaxy clusters and 6 large groups/small clusters. Comparison of these massive structures with published XMM-Newton imaging (where available) shows that 80% of these structures are associated with diffuse, soft-band (0.4-1keV) X-ray emission, including 90% of all objects classified as clusters. The presence of soft-band X-ray emission in these massive structures (M_200_{>=}4.9x10^13^M_{sun}_) provides a strong independent confirmation of our methodology and classification scheme. In the closest two clusters identified (z<0.13) high-quality optical ur photometric sample contains 5522 galaxies imaging from the Deep2c field of the Garching-Bonn Deep Survey reveals the cD galaxies and demonstrates that they sit at the center of the detected X-ray emission. Nearly 60% of the clusters, groups, and filaments are detected in the known enhanced density regions of the CDFS at z=~0.13, 0.52, 0.68, and 0.73. Additionally, all of the clusters, bar the most distant, are found in these overdense redshift regions. Many of the clusters and groups exhibit signs of ongoing formation seen in their velocity distributions, position within the detected cosmic web, and in one case through the presence of tidally disrupted central galaxies exhibiting trails of stars. These results all provide strong support for hierarchical structure formation up to redshifts of 1.2014AJ....147...52Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/147/52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/253 : Chandra Deep Field South: multi-colour data (Wolf+, 2008)VII/177 : Redshifts and Velocity Dispersions for Abell Clusters (Struble+ 1991)J/A+A/555/A42 : The XMM-CDFS catalogues (Ranalli+, 2013)J/MNRAS/425/2116 : Arizona CDFS Environment Survey, ACES (Cooper+, 2012)J/ApJS/189/270 : MUSYC optical imaging in ECDF-S (Cardamone+, 2010)J/ApJS/139/369 : Chandra Deep Field South. 1 Ms catalog (Giacconi+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/147/52https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/147/52http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/147/52https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/147/52https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/147/52http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/147/52GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/147/52/table2 (Catalog of overdensities in the Chandra Deep Field-South (CDFS))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/147/52/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/147/52/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/147/52/table2?GETtext/xml+votable180.050000true53.1225-27.9686110.0055555555555555566/35935 35957https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/147/52?format=asciidefaultJ/AJ/147/52/table2Catalog of overdensities in the Chandra Deep Field-South (CDFS)recnoRecord number assigned by the VizieR team.
