After removing >14000 X-ray point sources from the field, we smooth the remaining unresolved emission, tessellate it into segments of similar apparent surface brightness, and perform X-ray spectral fitting on those tessellates to infer the intrinsic properties of the X-ray-emitting plasma. By modeling faint resolved point sources, we estimate the contribution to the extended X-ray emission from unresolved point sources and show that the vast majority of Carina's unresolved X-ray emission is truly diffuse. Line-like correlated residuals in the X-ray spectral fits suggest that substantial X-ray emission is generated by charge exchange at the interfaces between Carina's hot, rarefied plasma and its many cold neutral pillars, ridges, and clumps.2011ApJS..194...15Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/194/15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/194/15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/194/15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/194/15https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/194/15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/194/15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/194/15/diffuse (Tessellate properties and their spectral fits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/15/diffuse?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/15/diffuse?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/15/diffuse?GETtext/xml+votable180.050000true162.16118-59.5531550.0055555555555555566/37333 37335 37930 38016 38017 38018https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/194/15?format=asciiX-raydefaultJ/ApJS/194/15/diffuseTessellate properties and their spectral fitschi2Model {chi}^2^stat.fit.chi2intdofModel degrees of freedomstat.fit.dofintrecnoRecord number assigned by the VizieR team.
