cds-question@unistra.frgalaxy-clustersx-ray-sourcesgalaxy-classification-systemsA reconstruction of the total mass (the fraction of dark matter, intercluster gas, and the brightest galaxy of the cluster) of 128 X-ray galaxy clusters at redshifts 0.01-1.4 based on Chandra observations is presented. The total mass M200 and the baryonic mass Mb have been measured for all the sample objects, as well as the concentration parameter c200, which characterizes the size of the dark matter halo. The existence of a tight correlation between c200 and M200 is confirmed, c{prop.to}M^a^_vir_/(1+z)b with a=-0.56+/-0.15 and b=0.80+/-0.25 (95% confidence level), in good agreement with the predictions of numerical simulations and previous observations. Fitting the inner dark-matter density slope {alpha} with a generalized NFW model yields {alpha}=1.10+/-0.48 at the 2{sigma} confidence level, combining the results for the entire sample, for which the model gives a good description of the data. There is also a tight correlation between the inner slope of the dark-matter density profile {alpha} and the baryonic mass contentMb for massive galaxy clusters, namely, {alpha} decreases with increasing baryonic mass content. A simple power-law model is used to fit the {alpha}-M_b_ distributions, yielding the break point for the inner slope of the dark-matter density profile b=1.72+/-0.37 (68% confidence level).2014AZh....91..679Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/91/679CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/91/679https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/91/679http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/91/679https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/91/679https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/91/679http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/91/679GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/91/679/catalog (Chandra observations, results of modeling the total mass profiles with Navarro-Frenk-White model (NFW) with slope {alpha}=1, and results for the dark matter profiles for the three-component fits (tables 1--3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/91/679/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/91/679/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/91/679/catalog?GETtext/xml+votable180.050000true10.4075-9.34250.0055555555555555566/206 207 306 2432 5094 5099 5483 5536 5585 5701 6539 7026 7178 7242 7273 7904 8220 8264 8268 8271 8520 8575 8691 8825 8921 9036 9168 9354 9363 9468 9498 9506 9776 9997 10312 10379 10527 10992 11195 11425 11467 11626 12121 12642 15112 16410 16434 16486 16543 16609 16702 16713 17141 17171 17237 17300 17457 17499 17769 18009 18016 18437 18746 18795 18800 19097 19608 20021 20355 20481 20507 20624 21766 22577 22607 22771 23027 23324 23451 24853 24943 25102 25188 25981 26037 26135 26177 26189 26208 26302 26785 26916 27075 27652 27962 28174 28430 28535 30946 31537 33235 33628 33894 34443 34668 35147 35950 36423 36846 38853 39077 39079 40615 40809 43627 43837 43838 43849 43977 44563 45421 45543 45984 47043 48076 48688 49012https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/91/679?format=asciiX-rayOpticaldefaultJ/AZh/91/679/catalogChandra observations, results of modeling the total mass profiles with Navarro-Frenk-White model (NFW) with slope {alpha}=1, and results for the dark matter profiles for the three-component fits (tables 1--3)SimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
