cds-question@unistra.frx-ray-sourcesgalaxiesvisible-astronomyredshiftedIn this paper we estimate the local (z<0.22) X-ray luminosity function of 'normal' galaxies derived from the XMM-Newton Needles in the Haystack Survey. This is an on-going project that aims to identify X-ray-selected normal galaxies (i.e. non-AGN dominated) in the local Universe. We are using a total of 70 XMM-Newton fields covering an area of 11deg^2^ which overlap with the Sloan Digital Sky Survey Data Release 2. Normal galaxies are selected on the basis of their resolved optical light profile, their low X-ray-to-optical flux ratio [log(fx/fo)<-2] and soft X-ray colours. We find a total of 28 candidate normal galaxies to the 0.58keV band flux limit of 2x10^-15^erg/cm2/s. Optical spectra are available for most sources in our sample (82 per cent). These provide additional evidence that our sources are bona fide normal galaxies with X-ray emission coming from diffuse hot gas emission and/or X-ray binaries rather than a supermassive black hole.2005MNRAS.360..782Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/360/782CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/xmm : XMM-Newton Observation Log (XMM-Newton Science Operation Center, 2002)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/360/782https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/360/782http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/360/782https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/360/782https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/360/782http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/360/782GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/360/782/table1 (The XMM-Newton pointings)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/360/782/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/360/782/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/360/782/table1?GETtext/xml+votable180.050000true10.62917-9.691390.005555555555555556Cone search capability for table J/MNRAS/360/782/table2 (The candidate normal galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/360/782/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/360/782/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/360/782/table2?GETtext/xml+votable180.050000true10.6861667-9.55451940.005555555555555556Cone search capability for table J/MNRAS/360/782/table3 (The excluded hard low-luminosity AGN)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/360/782/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/360/782/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/360/782/table3?GETtext/xml+votable180.050000true127.912958352.70190830.0055555555555555566/4124 4859 5091 5860 5975 5980 6056 6069 6098 7178 7210 7242 7281 7308-7309 7510 7552 8196 9457 9831 11112 11252 11337 11347 11354 11375 11392 11460-11461 11596 11787 11791 11932 11936 17237 17300 17749 17816 17840 17982 18387 18767 18780 19097 23149 23191 23209-23210 25585 25990 26019 26022 26028 26175 26292 26298 26975 27004 27102 27246 27428 27714 30029 31399 36733 367852.85864675833786e-19 3.5010283109654867e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/360/782?format=asciiX-rayOpticaldefaultJ/MNRAS/360/782/table1The XMM-Newton pointingsrecnoRecord number assigned by the VizieR team.
