cds-question@unistra.frgalaxy-clustersvisible-astronomyredshiftedWe have identified new clusters and characterized previously unknown Planck Sunyaev-Zeldovich (SZ) sources from the first Planck catalogue of SZ sources (PSZ1). The results presented here correspond to an optical follow-up observational programme developed during approximately one year (2014) at Roque de los Muchachos Observatory, using the 2.5m Isaac Newton telescope, the 3.5m Telescopio Nazionale Galileo, the 4.2m William Herschel telescope and the 10.4m Gran Telescopio Canarias. We have characterized 115 new PSZ1 sources using deep optical imaging and spectroscopy. We adopted robust criteria in order to consolidate the SZ counterparts by analysing the optical richness, the 2D galaxy distribution, and velocity dispersions of clusters. Confirmed counterparts are considered to be validated if they are rich structures, well aligned with the Planck PSZ1 coordinate and show relatively high velocity dispersion. Following this classification, we confirm 53 clusters, which means that 46% of this PSZ1 subsample has been validated and characterized with this technique. Sixty-two SZ sources (54% of this PSZ1 subset) remain unconfirmed. In addition, we find that the fraction of unconfirmed clusters close to the galactic plane (at |b|<25{deg}) is greater than that at higher galactic latitudes (|b|>25{deg}), which indicates contamination produced by radio emission of galactic dust and gas clouds on these SZ detections. In fact, in the majority of the cases, we detect important galactic cirrus in the optical images, mainly in the SZ target located at low galactic latitudes, which supports this hypothesis.2018A&A...616A..42Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/616/A42CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/91 : Planck Catalog of Compact Sources Release 1 (Planck, 2013)J/A+A/581/A14 : Updated Planck catalogue PSZ1 (Planck+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/616/A42https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/616/A42http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/616/A42https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/616/A42https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/616/A42http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/616/A42GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/616/A42/tablea1 (Clusters candidates from the PSZ1 catalogue studied in this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/616/A42/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/616/A42/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/616/A42/tablea1?GETtext/xml+votable180.050000true244.5841667-13.070.0055555555555555566/447 605 1008 2525 2798 2825 2912 3241 4086 4092 4094 6107 6658-6659 6731 6934 7495 7695 7845 7914 7954 8183 8530 9289 9867 9949 10070 10222 10897 11302 11381 11705 11864 12464 12827 12849 13675 13748 13941 14122 14144 14147 14208 14226 14841 15080-15081 15131 15831 15954 16112 16236 16349 17583 18083 18143 18263 18413 18427-18428 18975 19169 19248 19559 19616 19899 20027 20127 20161 20195 20261 21804 21938 22273 22467 22812 23142 23161 23427-23428 23461 23729 25881 26288 26568 27140 28013 29774 29796 29814 29818 29876 29992 30081 30197 30394 30537 30563 30767 31073 31093 31217 31225 31583 31841 31905 31996 32039 32054 32161 32199 32208 44533 44948 44997 49114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/616/A42?format=asciiOpticaldefaultJ/A+A/616/A42/tablea1Clusters candidates from the PSZ1 catalogue studied in this workR?
