cds-question@unistra.frx-ray-sourcesWe present results from two Chandra X-ray Observatory observations of the X-ray point source population in the nearby radio galaxy Centaurus A (NGC 5128). Using a wavelet decomposition detection algorithm, we detect 246 individual point sources above a limiting luminosity of ~2*10^36^ergs/s, 82 of which are detected in both data sets where the fields of view overlap. Thirty-eight sources were detected in only one observation but were within the field of view of both pointings, implying considerable variability. We identify eight foreground stars in our observations. We also identify nine of the sources with known globular clusters in Centaurus A. All previously observed ROSAT sources within our field of view are detected.2001ApJ...560..675Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/560/675CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/561/189 : Chandra X-ray sources in M101 (Pence+, 2001)J/ApJS/150/367 : Globular clusters in NGC 5128 (Peng+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/560/675https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/560/675http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/560/675https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/560/675https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/560/675http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/560/675GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/560/675/table2 (Summary of X-Ray point sources detected in Cen A observation)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/560/675/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/560/675/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/560/675/table2?GETtext/xml+votable180.050000true201.1102083-42.88589170.0055555555555555566/43262 43263https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/560/675?format=asciiX-raydefaultJ/ApJ/560/675/table2Summary of X-Ray point sources detected in Cen A observationrecnoRecord number assigned by the VizieR team.
