cds-question@unistra.frgalaxy-clustersmillimeter-astronomysubmillimeter-astronomyWe measure the 850-{mu}m source densities of 46 candidate protoclusters selected from the Planck high-z catalogue (PHz) and the Planck Catalogue of Compact Sources (PCCS) that were followed up with Herschel-SPIRE and SCUBA-2. This paper aims to search for overdensities of 850-{mu}m sources in order to select the fields that are most likely to be genuine protoclusters. Of the 46 candidate protoclusters, 25 have significant overdensities (>5 times the field counts), 11 have intermediate overdensities (3-5 times the field counts), and 10 have no overdensity (<3 times the field counts) of 850-{mu}m sources. We find that the enhanced number densities are unlikely to be the result of sample variance. Compared with the number counts of another sample selected from Planck's compact source catalogues, this [PHz + PCCS]-selected sample has a higher fraction of candidate protoclusters with significant overdensities, though both samples show overdensities of 850-{mu}m sources above intermediate level. Based on the estimated star formation rate densities (SFRDs), we suggest that both samples can efficiently select protoclusters with starbursting galaxies near the redshift at which the global field SFRD peaks (2<z<3). Based on the confirmation of overdensities found here, future follow-up observations on other PHz targets may greatly increase the number of genuine dusty star-forming galaxy-rich clusters/protoclusters.2020MNRAS.494.5985Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/494/5985CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/596/A100 : Planck high-z source candidates catalog (PHZ)J/A+A/594/A26 : Second Planck Catalogue of Compact Sources (PCCS2)J/MNRAS/465/1789 : SCUBA-2 Cosmology Legacy Survey (Geach+, 2017)J/MNRAS/468/4006 : Proto-cluster candidate fields (Mackenzie+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/494/5985https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/494/5985http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/494/5985https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/494/5985https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/494/5985http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/494/5985GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/494/5985/catalog (850 micron source catalogues for the 46 candidate protoclusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/494/5985/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/494/5985/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/494/5985/catalog?GETtext/xml+votable180.050000true324.9627306-8.78799860.0055555555555555566/4182-4183 4456-4457 4597 4599 4710-4711 4726 5280 5329 5412 5544-5545 5548 5550 5736-5737 5890 6514 6520 7238 7364 8377 8856-8857 9188 9575 9703 9720 9722 9969 10133 10790 11335 11417 11420 11557 16702 16725 16749 16855 16861 16881 17107 17204 17206 17223 17314 17524 17722 18736 18949 26519 28390 35817 35820 36529 36553 48497 48499 489832.3390025583187276e-22 2.3390025583187276e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/494/5985?format=asciiMillimeterdefaultJ/MNRAS/494/5985/table1Cumulative number counts of 46 candidate protoclusters in M17recnoRecord number assigned by the VizieR team.
