cds-question@unistra.frgalaxy-clusterssurveysredshiftedx-ray-sourcesWe introduce a galaxy cluster mass observable, {mu}_*_, based on the stellar masses of cluster members, and we present results for the Dark Energy Survey (DES) Year 1 (Y1) observations. Stellar masses are computed using a Bayesian model averaging method, and are validated for DES data using simulations and COSMOS data. We show that {mu}_*_ works as a promising mass proxy by comparing our predictions to X-ray measurements. We measure the X-ray temperature-{mu}_*_ relation for a total of 129 clusters matched between the wide-field DES Y1 redMaPPer catalogue and Chandra and XMM archival observations, spanning the redshift range 0.1<z<0.7. For a scaling relation that is linear in logarithmic space, we find a slope of {alpha}=0.488+/-0.043 and a scatter in the X-ray temperature at fixed {mu}_*_ of {sigma}_lnTX|{mu}*_= 0.266^+0.019^_-0.020_ for the joint sample. By using the halo mass scaling relations of the X-ray temperature from the Weighing the Giants program, we further derive the {mu}_*_-conditioned scatter in mass, finding {sigma}_lnM|{mu}*_=0.26^+0.15^_-0.10_. These results are competitive with well-established cluster mass proxies used for cosmological analyses, showing that {mu}_*_ can be used as a reliable and physically motivated mass proxy to derive cosmological constraints.2020MNRAS.493.4591Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/493/4591CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/357 : The Dark Energy Survey (DES): Data Release 1 (Abbott+, 2018)B/chandra : The Chandra Archive Log (CXC, 1999-2014)J/MNRAS/423/1024 : XCS-DR1 Cluster Catalogue (Mehrtens+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/493/4591https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/493/4591http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/493/4591https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/493/4591https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/493/4591http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/493/4591GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/493/4591/tablea1 (Chandra clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/493/4591/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/493/4591/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/493/4591/tablea1?GETtext/xml+votable180.050000true79.156-54.50.005555555555555556Cone search capability for table J/MNRAS/493/4591/tablea2 (XMM clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/493/4591/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/493/4591/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/493/4591/tablea2?GETtext/xml+votable180.050000true43.575-58.9510.0055555555555555566/18683 18779 18800 19043 19089 19097 19101 19111 33261 33273-33274 33564 33580 33586 33593 33598 33614 33618 33622 33628 33649 33668 33670 33692 33709 33711-33713 33718 33725 33735 33741 33764 33769 33783 33894 33897 33917 33945 33955-33956 33971 33990 34049 34083 34087 34139 34181 34186 34324 34350 34352 34355 34368 34461 34905 34910 34994 35032 35049 35067 35108 35147 35171 35180 35364 35382 35388 35417 35473 45893-45894 45904 45964-45966 45973 46001 46130 46171 46173-46174 46182 46192 46235 46237 46264 46341 46424 46474https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/493/4591?format=asciiX-raydefaultJ/MNRAS/493/4591/tablea1Chandra clustersRAJ2000Right ascension (J2000)degpos.eq.ra;meta.mainrecnoRecord number assigned by the VizieR team.
