cds-question@unistra.frsurveysx-ray-sourcesWe present a galaxy cluster survey based on XMM-Newton observations that are located in Stripe 82 of the Sloan Digital Sky Survey (SDSS). The survey covers an area of 11.25deg^2^. The X-ray cluster candidates were selected as serendipitously extended detected sources from the third XMM-Newton serendipitous source catalogue (3XMM-DR5). A cross-correlation of the candidate list that comprises 94 objects with recently published X-ray and optically selected cluster catalogues provided optical confirmations and redshift estimates for about half of the candidate sample. We present a catalogue of X-ray cluster candidates previously known in X-ray and/or optical bands from the matched catalogues or NED. The catalogue consists of 54 systems with redshift measurements in the range of 0.05-1.19 with a median of 0.36. Of these, 45 clusters have spectroscopic confirmations as stated in the matched catalogues. We spectroscopically confirmed another 6 clusters from the available spectroscopic redshifts in the SDSS-DR12. The cluster catalogue includes 17 newly X-ray discovered clusters, while the remainder were detected in previous XMM-Newton and/or ROSAT cluster surveys. Based on the available redshifts and fluxes given in the 3XMM-DR5 catalogue, we estimated the X-ray luminosities and masses for the cluster sample. We also present the list of the remaining X-ray cluster candidates (40 objects) that have no redshift information yet in the literature. Of these candidates, 25 sources are considered as distant cluster candidates beyond a redshift of 0.6. We also searched for galaxy cluster mergers in our cluster sample and found two strong candidates for newly discovered cluster mergers at redshifts of 0.11 and 0.26. The X-ray and optical properties of these systems are presented.2016A&A...594A..32Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/594/A32CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/46 : XMM-Newton Serendipitous Source Cat. 3XMM-DR5 (XMM-SSC, 2016)J/A+A/534/A120 : The 2XMMi/SDSS Galaxy Cluster Survey (Takey+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/594/A32https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/594/A32http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/594/A32https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/594/A32https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/594/A32http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/594/A32GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/594/A32/tablec1 (Galaxy cluster catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/594/A32/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/594/A32/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/594/A32/tablec1?GETtext/xml+votable180.050000true2.81470.864620.005555555555555556Cone search capability for table J/A+A/594/A32/tablec2 (Cluster candidate catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/594/A32/tablec2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/594/A32/tablec2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/594/A32/tablec2?GETtext/xml+votable180.050000true1.153460.030280.0055555555555555566/0 17749 17767 17772-17773 17812-17813 17817 17819 18006 18028 18032 18069 18071-18073 18084 18090 18092 18096 18112 18114 18773 18789-18791 18796 19025 19033-19036 19091 23145 23148 23196 23208-23210https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/594/A32?format=asciiX-raydefaultJ/A+A/594/A32/tablec1Galaxy cluster cataloguerecnoRecord number assigned by the VizieR team.
