cds-question@unistra.frgalaxy-clustersredshiftedThe CAIRNS (Cluster and Infall Region Nearby Survey) project is a spectroscopic survey of the infall regions surrounding eight nearby, rich, X-ray-luminous clusters of galaxies. We have collected 15654 redshifts (3471 new or remeasured) within ~5-10h^-1^Mpc of the centers of the clusters, making it the largest study of the infall regions of clusters. We determine cluster membership and the mass profiles of the clusters based on the phase-space distribution of the galaxies. All of the clusters display decreasing velocity dispersion profiles. The mass profiles are fitted well by functional forms based on numerical simulations but exclude an isothermal sphere. Specifically, Navarro et al. (1997ApJ...490..493N) and Hernquist (1990ApJ...356..359H) models provide good descriptions of cluster mass profiles to their turnaround radii. Our sample shows that the predicted infall pattern is ubiquitous in rich, X-ray-luminous clusters over a large mass range. The caustic mass estimates are in excellent agreement with independent X-ray estimates at small radii and with virial estimates at intermediate radii. The mean ratio of the caustic mass to the X-ray mass is 1.03+/-0.11, and the mean ratio of the caustic mass to the virial mass (when corrected for the surface pressure term) is 0.93+/-0.07. We further demonstrate that the caustic technique provides reasonable mass estimates even in merging clusters.2003AJ....126.2152Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/126/2152CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/120/2338 : Abell 576 redshifts (Rines+, 2000)J/AJ/124/1266 : Redshift survey around Abell 2199 (Rines+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/126/2152https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/126/2152http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/126/2152https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/126/2152https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/126/2152http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/126/2152GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/126/2152/clusters (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/126/2152/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/126/2152/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/126/2152/clusters?GETtext/xml+votable180.050000true14.05375-1.2350.005555555555555556Cone search capability for table J/AJ/126/2152/galaxies (Spectroscopic properties of galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/126/2152/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/126/2152/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/126/2152/galaxies?GETtext/xml+votable180.050000true9.1217917-0.72861110.0055555555555555563/162 4/643 1114-1115 1125-1127 1411 1741 1743 1759 1767 1781 5/2562 2568 2570 2584 2586-2587 2608-2610 2616 2618 2689-2691 2693-2694 2696-2697 4383 4398-4399 4401 4404 4406 4409 4414-4415 4450-4452 4454 4485-4487 4492-4493 4495-4496 4498-4499 4517 4528-4529 4544-4546 4548 4550 4552 4555 5632 5634 5636-5637 5639-5641 5643 5650 5656 5658-5659 5668-5669 5734 5741 5743-5744 5747 5750-5751 5753 5755-5756 5758-5759 5840-5841 5844 5928 6956 6958-6960 6968-6969 6971 7005-7008 7010 7016-7018 7022 7029 7031-7032 7041 7053 7056-7057 7059 7061-7065 7067 7090-7094 7104-7106 7109-7110 7112-7113 7116 7118-7119 7121-7123 7132-7133 7136 6/7026 9468 10242 10247 10252 10254-10255 10259 10265-10267 10269-10271 10276-10277 10279 10285-10287 10314 10340 10342 10444-10445 10447 10456 10469-10471 10476-10477 10752 10754-10755 10768-10769 10771 10780-10782 10793 10796 10800-10802 10816-10818 10824 17463 17469-17471 17506-17507 17511-17513 17515-17517 17519 17521-17523 17526 17529-17530 17549 17553 17556-17558 17562 17564-17566 17575 17581 17584-17585 17589-17591 17601-17603 17609 17611-17614 17621-17623 17628-17630 17633-17635 17641 17643 17645-17650 17652 17654-17655 17698-17699 17704 17706-17708 17711 17722 17793-17797 17799 17814 17820 17822-17823 17896 17898 17925 17927 17937 17939 17976-17977 17979 17988 17990-17991 18065 18120 18124 18128 18130-18131 18133-18134 18188-18190 18196 18198-18199 18204-18206 18212 18214-18217 18219 18226 18228-18229 18231-18232 18234-18236 18238 18240 18242 18248 18250 18304 18306-18307 18309 18311-18312 18320-18322 18324 21165-21167 21176 21178-21179 21182-21183 22533-22535 22540-22541 22543 22553-22555 22569 22571 22592 22594-22595 22604 22606 22628 22630 22661 22720-22722 22724 22831 22834-22835 22840-22841 22845-22847 22875 22889-22890 22892-22893 22899 22905 22907-22908 22917 22919 22925 22929-22932 22934-22935 22940 22942-22943 22949 22951 22959 22961 22963 22968-22970 22980 22982-22983 22985-22986 22993-22995 22998-22999 23009-23011 23016-23017 23019 23028-23030 23312-23313 23315 23319 23324 23326 23349 23370-23371 23374-23375 23380-23382 23384-23385 23387 23390-23391 23393 23396-23398 23404-23405 23408-23409 23593 23681-23682 23684 23688-23690 23694-23695 23705-23706 23720-23722 23725 23728 23734 24091 24100 27799 27802-27803 27805-27806 27815 27821 27823 27828 27830-27831 27844-27846 27848-27849 27851 27853-27855 27880-27881 27883 27967 27981-27983 27986-27987 27990 27994 27996 27998 28003-28005 28007-28010 28015 28017-28019 28038 28044-28046 28053-28055 28058-28060 28062 28076-28078 28081-28082 28085-28087 28092 28095 28097-28100 28102 28106-28110 28112-28113 28115 28121-28123 28132 28134-28135 28137-28139 28141-28143 28173-28178 28180-28181 28184 28188-28189 28191 28205 28208-28209 28218 28220-28221 28232 28234-28235 28241-28243 28264-28265 28267 28304-28305 28307 28309-28311 28317 28319 28352-28353 28355-28356 28358-28359 28380-28381 28383 28385 28388 28400 28402-28406 28428-28430 28432 28434-28435 28444 28446-28447 28456 28458-28461 28463 28468-28469 28471 28481-28483 28512-28513 28516-28517 28519 28536-28537 28540 28548-28549 28551-28552 28554-28557 28560 28562-28564 28568-28569 28576-28578https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/126/2152?format=asciiOpticaldefaultJ/AJ/126/2152/clustersCombined table from original tablesrecnoRecord number assigned by the VizieR team.
