We find 629 ULX candidates in 309 galaxies with distance smaller than 40Mpc. The foreground/background contamination is ~20 per cent. The ULX populations in bona fide star-forming galaxies scale on average with star formation rate and stellar mass (M_*_) such that the number of ULXs per galaxy is 0.45^+0.06^_-0.09_xSFR/(M_{sun}_/yr)+3.3^+3.8^_-3.2_xM_*_/M_{sun}_. The scaling depends strongly on the morphological type. This analysis shows that early spiral galaxies contain an additional population of ULXs that scales with M_*_. We also confirm the strong anticorrelation of the ULX rate with the host galaxy's metallicity. In the case of early-type galaxies, we find that there is a non-linear dependence of the number of ULXs with M_*_, which is interpreted as the result of star formation history differences. Taking into account age and metallicity effects, we find that the predictions from X-ray binary population synthesis models are consistent with the observed ULX rates in early-type galaxies, as well as spiral/irregular galaxies. 2020MNRAS.498.4790K https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/498/4790 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to IX/57 : The Chandra Source Catalog (CSC), Release 2.0 (Evans+, 2019) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/498/4790 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/498/4790 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/498/4790 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/498/4790 https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/498/4790 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/498/4790 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/MNRAS/498/4790/table1 (Parameters of the 2218 host galaxies) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/498/4790/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/498/4790/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/498/4790/table1?
