cds-question@unistra.fractive-galactic-nucleix-ray-sourcesWe present an XMM-Newton observation of the massive edge-on Sb galaxy NGC 2613. We discover that this galaxy contains a deeply embedded active nucleus with a 0.3-10keV luminosity of 3.3x10^40^erg/s and a line-of-sight absorption column of 1.2x10^23^cm^-2^. Within the 25mag arcsec-2 optical B-band isophote of the galaxy, we detect an additional four sources with an accumulated luminosity of 4.3x10^39^erg/s. The bulk of the unresolved X-ray emission spatially follows the near-infrared (NIR) K-band surface brightness distribution; the luminosity ratio LX/LK~8x10^-4^ is consistent with that inferred from galactic discrete sources. This X-ray-NIR association and the compatibility of the X-ray spectral fit with the expected spectrum of a population of discrete sources suggest that low-mass X-ray binaries (LMXBs) are the most likely emitters of the unresolved emission in the disc region.2006MNRAS.371..147Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/371/147CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/371/83 : XMM obs. of Arches & Quintuplet clusters (Wang+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/371/147https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/371/147http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/371/147https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/371/147https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/371/147http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/371/147GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/371/147/table2 (XMM-Newton source list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/147/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/147/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/147/table2?GETtext/xml+votable180.050000true128.1190417-22.97791670.0055555555555555566/40514 40520https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/371/147?format=asciiX-raydefaultJ/MNRAS/371/147/table2XMM-Newton source listrecnoRecord number assigned by the VizieR team.
