As demonstrated by Planck, galaxy clusters detected via the Sunyaev-Zel'dovich (SZ) effect offer a powerful way to constrain cosmological parameters such as $\Omega_{\mathrm{m}}$ and $\sigma_8$. Determining the absolute cluster mass scale is, however, difficult, and some recent calibrations have yielded cosmological constraints in apparent tension with constraints in the $\Lambda$CDM model derived from the power spectra of the primary CMB anisotropies. In order to calibrate the absolute mass scale of the full Planck cluster sample, we remeasure the masses of all 433 clusters through their weak lensing signature in the CMB temperature anisotropies as measured by Planck. We perform a joint Bayesian analysis of the cluster counts and masses taking as input the estimated cluster masses, SZ signal-to-noise ratios, and redshifts. Our analysis properly accounts for selection effects in the construction of the cluster sample. We find $\sigma_8 \left(\Omega_{\mathrm{m}}/0.33\right)^{0.25} = 0.765 \pm 0.035$ and $1-b_{\mathrm{SZ}} = 0.71 \pm 0.10$, where the mass bias factor $1-b_{\mathrm{SZ}}$ relates cluster mass to the SZ mass that appears in the X-ray-calibrated cluster scaling relations. We find no evidence for tension with the Planck primary CMB constraints on $\Lambda$CDM model parameters. dc.publisher Oxford University Press dc.rights All rights reserved dc.rights.uri dc.subject galaxies: clusters: general en dc.subject Cosmology en dc.subject cosmic background radiation en dc.subject cosmological parameters en dc.title Cosmological constraints from Planck galaxy clusters with CMB lensing mass bias calibration en dc.type Article prism.endingPage 419 prism.issueIdentifier 1 en prism.publicationDate 2019 en prism.publicationName MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY en prism.startingPage 401 prism.volume 489 en dc.identifier.doi 10.17863/CAM.43532 dcterms.dateAccepted 2019-07-22 en rioxxterms.versionofrecord 10.1093/mnras/stz2153 en rioxxterms.version VoR rioxxterms.licenseref.uri http://www.rioxx.net/licenses/all-rights-reserved en rioxxterms.licenseref.startdate 2019-10 en dc.contributor.orcid Challinor, Anthony [0000-0003-3479-7823] dc.identifier.eissn 1365-2966 rioxxterms.type Journal Article/Review en pubs.funder-project-id SCIENCE & TECHNOLOGY FACILITIES COUNCIL (ST/N000927/1)
