cds-question@unistra.frgalaxy-clustersredshiftedWe characterized the population of galaxy clusters detected with the Sunyaev-Zeldovich (SZ) effect with Planck by measuring the cool-core state of the objects in a well-defined subsample of the Planck SZ catalogue. We used as an indicator the concentration parameter. The fraction of cool-core clusters is 29+/-4 per cent and does not show significant indications of evolution in the redshift range covered by our sample. We compare the distribution of the concentration parameter in the Planck sample with the one of the X-ray selected sample MACS: the distributions are significantly different and the cool-core fraction in MACS is much higher (59+/-5 per cent) than that in Planck. Since X-ray-selected samples are known to be biased towards cool cores due to the presence of their prominent surface brightness peak, we simulated the impact of the 'cool-core bias'. We found that this bias plays a large role in the difference between the fractions of cool cores in the two samples. We examined other selection effects that could in principle bias SZ surveys against cool cores, but we found that their impact is not sufficient to explain the difference between Planck and MACS. The population of X-ray underluminous objects, which are found in SZ surveys but missing in X-ray samples, could possibly contribute to the difference, as we found most of them to be non-cool cores, but this hypothesis deserves further investigation.2017MNRAS.468.1917Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/468/1917CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/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/MNRAS/468/1917https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/468/1917http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/468/1917https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/468/1917https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/468/1917http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/468/1917GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/468/1917/table1 (Properties of the clusters in our Planck sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/468/1917/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/468/1917/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/468/1917/table1?GETtext/xml+votable180.050000true334.66525-38.89972220.005555555555555556Cone search capability for table J/MNRAS/468/1917/table2 (Properties of the clusters in the ME-MACS sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/468/1917/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/468/1917/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/468/1917/table2?GETtext/xml+votable180.050000true216.51337.82358330.0055555555555555566/821 4206 4406 4512 4965 5099 5299 5597 5701 5795 5931 5985 6011 6019 6088 6337 6383 6441 6539 6873 7026 7242 7513 7768 7904 7928 8033 8066 8220 8338 8520 8921 8969 9036 9050 9052 9168 9354 9466 9476 9498 9506 9508 9593 9997 10312 10318 10527 10607 10664 11042 11063 11080 11253 11264 11591 11626 11672 11809 11901 11974 12121 12642 12653 13314 13384 15112 15286 15345 16411 16434 16486 16609 16702 16713 16787 17171 17222 17237 17457 17499 17618 18016 18034 18328 18475 18534 18566 18800 18894 19009 19089 19097 19101 19848 19935 20302 20481 20507 20536 20624 20874 21073 21211 21766 22607 22661 22771 22792 22915 22949 22955 22972 23173 23192 23349 23366 23474 24822 24943 25188 25391 25451 25675 26037 26135 26177 26189 26208 26302 26707 27075 27136 27428 27476 27660 27742 28086 28181 28429-28430 28448 28622 30946 31537 32379 32500 32798 32894 32960 33030 33034 33152 33235 33289 33321 33474 33614 33628 33649 33692 33894 33945 34087 34159 34165 34174 34181 34324 34443 34726 34793 35043 35147 35171 35310 35696 35808 35950 36082 36089 36423 36434 38858 38973 39067-39068 39077 39443 39608 40564 40809 41079 41081 43358 43706 43838 43849 43939 43948 43977 44563 44697 44802 44817 45044 45421 45506 45543 45562 45966 45984 46237 46444 46474 46540 46571 46687 46855 46889 47043 47139 47188 47225 47573 48076 48174 48272 48423 48489 48688 48735 48966 49012https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/468/1917?format=asciidefaultJ/MNRAS/468/1917/table1Properties of the clusters in our Planck samplerecnoRecord number assigned by the VizieR team.
