cds-question@unistra.frgalaxy-clustersx-ray-sourcesThe X-ray regime, where the most massive visible component of galaxy clusters, the intracluster medium, is visible, offers directly measured quantities, like the luminosity, and derived quantities, like the total mass, to characterize these objects. The aim of this project is to analyse a complete sample of galaxy clusters in detail and constrain cosmological parameters, like the matter density, {Omega}_m_, or the amplitude of initial density fluctuations, {sigma}_8_. The purely X-ray flux-limited sample (HIFLUGCS) consists of the 64 X-ray brightest galaxy clusters, which are excellent targets to study the systematic effects, that can bias results. We analysed in total 196 Chandra observations of the 64 HIFLUGCS clusters, with a total exposure time of 7.7Ms. Here, we present our data analysis procedure (including an automated substructure detection and an energy band optimization for surface brightness profile analysis) that gives individually determined, robust total mass estimates. These masses are tested against dynamical and Planck Sunyaev-Zeldovich (SZ) derived masses of the same clusters, where good overall agreement is found with the dynamical masses. The Planck SZ masses seem to show a mass-dependent bias to our hydrostatic masses; possible biases in this mass-mass comparison are discussed including the Planck selection function. Furthermore, we show the results for the (0.1-2.4)keV luminosity versus mass scaling relation. The overall slope of the sample (1.34) is in agreement with expectations and values from literature. Splitting the sample into galaxy groups and clusters reveals, even after a selection bias correction, that galaxy groups exhibit a significantly steeper slope (1.88) compared to clusters (1.06).2017MNRAS.469.3738Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/469/3738CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/469/3738https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/469/3738http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/469/3738https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/469/3738https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/469/3738http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/469/3738GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/469/3738/tableb2 (Properties of the 64 HIFLUGCS clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/469/3738/tableb2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/469/3738/tableb2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/469/3738/tableb2?GETtext/xml+votable180.050000true54.6678922229.9679970.0055555555555555566/50 87 206-207 306 2251 2432 7026 8220 8264 8268 8271 8520 9036 9354 9468 9506 10312 10379 11591 12121 16434 16543 16713 17141 17237 18016 19608 20021 20355 20481 22577 22722 23306 23451 24943 24951 25981 26135 26208 26302 26313 27652 28249 30946 31537 33235 33628 34443 34535 38853 39077 39079 40777 40809 43627 43837-43838 43849 43977 44554 45044 45984 46484https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/469/3738?format=asciiX-raydefaultJ/MNRAS/469/3738/tableb2Properties of the 64 HIFLUGCS clustersSimbadNameSimbad column added by the CDSmeta.idcharNameCluster namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
