cds-question@unistra.frmagellanic-cloudsx-ray-sourcesWe have detected 523 sources in a survey of the Small Magellanic Cloud (SMC) Wing with Chandra. By cross-correlating the X-ray data with optical and near-infrared catalogues, we have found 300 matches. Using a technique that combines X-ray colours and X-ray to optical flux ratios, we have been able to assign preliminary classifications to 265 of the objects. Our identifications include four pulsars, one high-mass X-ray binary (HMXB) candidate, 34 stars and 185 active galactic nuclei (AGN). In addition, we have classified 32 sources as hard AGN which are likely absorbed by local gas and dust, and nine soft AGN whose nature is still unclear. Considering the abundance of HMXBs discovered so far in the Bar of the SMC the number that we have detected in the Wing is low.2008MNRAS.383..330Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/383/330CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/136/81 : A ROSAT PSPC X-Ray Survey of the SMC (Kahabka, 1999)J/A+AS/142/41 : SMC X-ray sources ROSAT PSPC catalogue (Haberl+, 2000)J/A+AS/147/75 : ROSAT HRI catalogue of SMC X-ray sources (Sasaki+, 2000)J/PASJ/55/161 : ASCA sources in the SMC (Yokogawa+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/383/330https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/383/330http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/383/330https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/383/330https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/383/330http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/383/330GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/383/330/table2 (The SMC Wing Survey catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/383/330/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/383/330/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/383/330/table2?GETtext/xml+votable180.050000true13.6477917-73.3280.0055555555555555566/33293 33295 33298-33299 33304-33306 33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/383/330?format=asciiX-raydefaultJ/MNRAS/383/330/table2The SMC Wing Survey cataloguerecnoRecord number assigned by the VizieR team.
