cds-question@unistra.frsurveysgalaxiescatalogsgalaxy-clustersredshiftedmillimeter-astronomysubmillimeter-astronomyphotometryThe South Pole Telescope third-generation camera (SPT-3G) has observed over 10000 square degrees of sky at 95, 150, and 220GHz (3.3, 2.0, 1.4mm, respectively) and will significantly overlap the ongoing 14,000 square-degree Euclid Wide Survey. The Euclid collaboration recently released Euclid Deep Field South (EDF-S) observations of 23 square degrees at Wide Field depths in the first quick data release (Q1). With the goal of releasing complementary millimeter-wave data and encouraging legacy science, we performed dedicated observations of a 57-square-degree field overlapping the EDF-S. The observing time totaled 20 days and we reached noise depths of 4.3, 3.8, and 13.2uK-arcmin at 95, 150, and 220GHz, respectively. In this work we present the temperature maps and two catalogs constructed from these data. The emissive source catalog contains 601 objects (334 inside EDF-S) with 54% synchrotron-dominated sources and 46% thermal dust emission-dominated sources. The 5{sigma} detection thresholds are 1.7, 2.0, and 6.5mJy in the three bands. The cluster catalog contains 217 cluster candidates (121 inside EDF-S) with median mass M_500c_=2.12x10^14^M_{sun}_/h_70_ and median redshift z=0.70, corresponding to an order-of-magnitude improvement in cluster density over previous tSZ-selected catalogs in this region (3.81 clusters per square degree). The overlap between SPT and Euclid data will enable a range of multiwavelength studies of the aforementioned source populations. This work serves as the first step towards joint projects between SPT and Euclid and provides a rich dataset containing information on galaxies, clusters, and their environments.2026A&A...706A..17Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/706/A17CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/706/A17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/706/A17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/706/A17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/706/A17https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/706/A17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/706/A17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/706/A17/cluster (Cluster catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/706/A17/cluster?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/706/A17/cluster?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/706/A17/cluster?GETtext/xml+votable180.050000true54.3608069753837-50.77917394457570.005555555555555556Cone search capability for table J/A+A/706/A17/emsource (Point source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/706/A17/emsource?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/706/A17/emsource?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/706/A17/emsource?GETtext/xml+votable180.050000true59.3689547822-46.42853290560.005555555555555556Cone search capability for table J/A+A/706/A17/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/706/A17/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/706/A17/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/706/A17/list?GETtext/xml+votable180.050000true61.25-48.750.0055555555555555564/2145 5/8493 8495 8506-8507 8578-8579 8584-8585 8588 8592 6/33631 33653 33655 33977-33979 34018-34019 34022 34040 34307 34309-34311 34345-34346 34348-34349 34351 34356-34358 34360-34362 34372-34374 34376-343786.294766091792609e-23 1.4577353054677622e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/706/A17?format=asciiMillimeterdefaultJ/A+A/706/A17/clusterCluster catalogrecnoRecord number assigned by the VizieR team.
