cds-question@unistra.frgalaxiesx-ray-sourcesWe present an X-ray study of the massive edge-on Sa galaxy, Sombrero (M 104; NGC 4594), based on XMM-Newton and Chandra observations. A list of 62 XMM-Newton and 175 Chandra discrete X-ray sources is provided, the majority of which are associated with the galaxy. Spectral analysis is carried out for relatively bright individual sources and for an accumulated source spectrum.2007MNRAS.376..960Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/376/960CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/599/1067 : X-ray sources in M104 (Di Stefano+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/376/960https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/376/960http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/376/960https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/376/960https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/376/960http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/376/960GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/376/960/table2 (Chandra source list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/376/960/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/376/960/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/376/960/table2?GETtext/xml+votable180.050000true189.874125-11.76386110.005555555555555556Cone search capability for table J/MNRAS/376/960/table3 (XMM-Newton source list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/376/960/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/376/960/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/376/960/table3?GETtext/xml+votable180.050000true189.72775-11.62636110.005555555555555556Cone search capability for table J/MNRAS/376/960/table4 (Matching results with 2MASS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/376/960/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/376/960/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/376/960/table4?GETtext/xml+votable180.050000true189.9115-11.64755560.0055555555555555566/25081 25083https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/376/960?format=asciiX-raydefaultJ/MNRAS/376/960/table2Chandra source liste_HR? rms uncertainty on HRstat.errorfloatnullablerecnoRecord number assigned by the VizieR team.
