cds-question@unistra.frgalaxy-clustersradio-continuum-emissionThe thermal Sunyaev-Zel'Dovich (tSZ) effect is expected to provide a low scatter mass proxy for galaxy clusters since it is directly proportional to the cluster thermal energy. The tSZ observations have proven to be a powerful tool for detecting and studying them, but high angular resolution observations are now needed to push their investigation to a higher redshift. In this paper, we report high angular (<20-arcsec) resolution tSZ observations of the high-redshift cluster CL J1226.9+3332 (z=0.89). It was imaged at 150 and 260GHz using the NIKA camera at the IRAM 30-meter telescope. The 150GHz map shows that CL J1226.9+3332 is morphologically relaxed on large scales with evidence of a disturbed core, while the 260GHz channel is used mostly to identify point source contamination. NIKA data are combined with those of Planck and X-ray from Chandra to infer the cluster's radial pressure, density, temperature, and entropy distributions. The total mass profile of the cluster is derived, and we find M_500_=5.96^+1.02^_-0.79_x10^14^M_{sun} within the radius R_500_=930^+50^_-43kpc, at a 68% confidence level. (R_500_ is the radius within which the average density is 500 times the critical density at the cluster's redshift.) NIKA is the prototype camera of NIKA2, a KIDs (kinetic inductance detectors) based instrument to be installed at the end of 2015. This work is, therefore, part of a pilot study aiming at optimizing tSZ NIKA2 large programs.2015A&A...576A..12Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/576/A12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/576/A12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/576/A12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/576/A12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/576/A12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/576/A12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/576/A12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/576/A12/list (List of FITS images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/576/A12/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/576/A12/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/576/A12/list?GETtext/xml+votable180.050000true186.7416733.544440.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/576/A126/28535https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/576/A12?format=asciiRadiodefaultJ/A+A/576/A12/listList of FITS imagesrecnoRecord number assigned by the VizieR team.
