cds-question@unistra.frsurveysx-ray-sourcesgalaxiescatalogsWe compile a sample of X-ray-selected galaxy groups and clusters from the XMM-Newton serendipitous source catalogue (2XMMi-DR3) with optical confirmation and redshift measurement from the Sloan Digital Sky Survey (SDSS). The X-ray cluster candidates were selected from the 2XMMi-DR3 catalogue in the footprint of the SDSS-DR7. We developed a finding algorithm to search for overdensities of galaxies at the positions of the X-ray cluster candidates in the photometric redshift space and to measure the redshifts of the clusters from the SDSS data. The detection algorithm provides the photometric redshift of 530 galaxy clusters. Of these, 310 clusters have a spectroscopic redshift for at least one member galaxy. About 75 percent of the optically confirmed cluster sample are newly discovered X-ray clusters. Moreover, 301 systems are known as optically selected clusters in the literature while the remainder are new discoveries in X-ray and optical bands. The optically confirmed cluster sample spans a wide redshift range 0.03-0.70 (median z=0.32). In this paper, we present the catalogue of X-ray-selected galaxy groups and clusters from the 2XMMi/SDSS galaxy cluster survey. The catalogue has two subsamples: (i) a cluster sample comprising 345 objects with their X-ray spectroscopic temperature and flux from the spectral fitting, and (ii) a cluster sample consisting of 185 systems with their X-ray flux from the 2XMMi-DR3 catalogue, because their X-ray data are insufficient for spectral fitting. The updated L_X_-T relation of the current sample with X-ray spectroscopic parameters is presented. We see no evidence for evolution in the slope and intrinsic scatter of the L_X_-T relation with redshift when excluding the low-luminosity groups2013A&A...558A..75Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/558/A75CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/39 : XMM-Newton 2nd Serendipitous Source Catalogue (2XMM, 2007)IX/41 : XMM-Newton Serendipitous Source Catalogue 2XMMi-DR3 (XMM-SSC, 2010)J/A+A/534/A120 : 2XMMi/SDSS Galaxy Cluster Survey (Takey+, 2011)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/558/A75https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/558/A75http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/558/A75https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/558/A75https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/558/A75http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/558/A75GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/558/A75/table1 (The 2XMMi/SDSS Galaxy Cluster Survey (II), sub- 1 (TX and FX from spectral fitting))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/558/A75/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/558/A75/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/558/A75/table1?GETtext/xml+votable180.050000true4.571916.29470.005555555555555556Cone search capability for table J/A+A/558/A75/table2 (The 2XMMi/SDSS Galaxy Cluster Survey (II), sub- 2 (TX and FX from 2XMMi-DR3 catalog))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/558/A75/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/558/A75/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/558/A75/table2?GETtext/xml+votable180.050000true10.52296-9.603750.0055555555555555566/399 924 926 2229 2248 2251 4227 4315 4327 4345 4347-4348 4352 4369 4403 4409 4438-4439 4448 4488 4567 4597 4653 4672 4689 4698 4750 4790 4804 4831 4862 4955 4964-4965 4976-4977 4993 5018 5033 5091 5130 5241 5244 5246 5284 5304 5312-5313 5333 5369-5370 5420 5423 5429 5437-5438 5471 5538 5560 5568 5576 5604 5629-5630 5669 5675 5687 5689 5727 5731-5732 5762 5798 5862 5864 5914 5922 5928 5936 5952 5974-5976 5980 6009 6018 6033 6051 6059 6069 6073 6078 6098 6124 6247 6440 6470 6574 6641 6645 7178 7273 7280-7281 7309 7323 7345 7349 7375 7428 7444 7446 7456 7485 7522 7552 7604 7777 8203 8225 8339 8644 8673 8845 8922-8923 8927 8947 8956 9018 9074 9112 9149-9150 9242 9415 9421 9457 9459 9469 9490 9632 9750 9895 10153 10182 10223 10238 10255 10321 10364 10378-10379 10383 10389 10391 10401 10414 10420 10422 10434 10440 10444 10465 10472 10474 10484 10549 10598-10599 10605 10691 10694 10761 10905 10912 10924-10925 10927 10936 10938 10979 10982 11000 11029 11048 11050 11074 11080-11081 11084 11101 11112 11114 11127 11130 11158 11208-11209 11217 11252 11314 11347 11352 11355 11392 11514 11596 11603 11785 11791 11806 11810 11829 11831 11856 11924 11932 12317 13511 16034 16784 17237 17497 17503 17582 17727 17812 17819 18028 18032 18069 18071 18084 18092 18096 18112 18114 18234-18235 18241 18367 18591 18601 18968 19023 19045 19097 19298 19383 19842 19848 19943 19954 21851 21870 22651 23145 23191 23196 23208-23210 25084 25586 25855 25906 25919 25946 25956 25974-25975 25982 25986 26018 26022 26125 26169 26175 26289 26292 26331 26379 26427 26432 26454 26509 26563 26867 26990 26997-26998 27004-27005 27026 27081 27088 27102 27122 27126 27132 27235 27256 27258-27259 27307 27342-27343 27423 27440 27460 27462 27466 27486 27491 27536 27617 27658 27664 27718 27720 27734 27742 27765 27857 27861-27862 27934 27938 27941 27950 27955 27963 27982 28019 28032 28062 28124 28126-28127 28141-28143 28148 28173 28209 28221 28230 28334 28344 28346 28415 28495 28517 28535 28621 31354 31399 31401 31652 36733 36775 36780 36786 36792 45054 49009https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/558/A75?format=asciiX-raydefaultJ/A+A/558/A75/table1The 2XMMi/SDSS Galaxy Cluster Survey (II), sub- 1 (TX and FX from spectral fitting)q_zmeta.code.qualcharrecnoRecord number assigned by the VizieR team.
