cds-question@unistra.frgalaxy-clustersredshiftedastronomical-object-identificationsurveysWe use photometric redshifts derived from new u-band through 4.5{mu}m Spitzer IRAC photometry in the 4.8deg^2^ of the XMM-LSS field to construct surface density maps in the redshift range of 0.1-1.5. Our density maps show evidence for large-scale structure in the form of filaments spanning several tens of megaparsecs. Using these maps, we identify 339 overdensities that our simulated light-cone analysis suggests are likely associated with dark matter halos with masses, M_halo_, log(M_halo_/M_{sun}_)>13.7. From this list of overdensities we recover 43 of 70 known X-ray-detected and spectroscopically confirmed clusters. The missing X-ray clusters are largely at lower redshifts and lower masses than our target log(M_halo_/M_{sun}_)>13.7. The bulk of the overdensities are compact, but a quarter show extended morphologies that include likely projection effects, clusters embedded in apparent filaments, and at least one potential cluster merger (at z~1.28). The strongest overdensity in our highest-redshift slice (at z~1.5) shows a compact red galaxy core, potentially implying a massive evolved cluster.2020ApJ...889..185Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/889/185CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/334 : VISTA Deep Extragalactic Observations (VIDEO) (Jarvis+, 2013)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)J/A+A/556/A55 : Multi-color photometry of star-forming galaxies (Ilbert+, 2013)J/A+A/559/A14 : VIMOS VLT Deep Survey final data release (Le Fevre+, 2013)J/ApJ/805/121 : Overdensities of 0<z<3 COSMOS galaxies (Darvish+, 2015)J/ApJS/224/24 : The COSMOS2015 catalog (Laigle+, 2016)J/ApJS/230/9 : Improved multi-band photometry from SERVS (Nyland+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/889/185https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/889/185http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/889/185https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/889/185https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/889/185http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/889/185GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/889/185/table3 (Overdensities selected in the XMM-LSS field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/889/185/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/889/185/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/889/185/table3?GETtext/xml+votable180.050000true36.7988-5.06980.0055555555555555565/4422 6/17677 17679 17683 17686 17692 17712https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/889/185?format=asciidefaultJ/ApJ/889/185/table3Overdensities selected in the XMM-LSS fieldr_zRedshift reference(s) (2)meta.ref;pos.framecharrecnoRecord number assigned by the VizieR team.
