cds-question@unistra.frx-ray-sourcesUltraluminous X-ray sources (ULXs) are some of the most enigmatic X-ray bright sources known to date. It is generally accepted that they cannot host black holes as large as those associated with active galaxies, but they appear to be significantly more luminous than their better understood Galactic X-ray binary (XRB) cousins, while displaying an intriguing combination of differences and similarities with them. Through studying large, representative samples of these sources we may hope to enhance our understanding of them. To this end, we derive a large catalogue of 650 X-ray detections of 470 ULX candidates, located in 238 nearby galaxies, by cross-correlating the 2XMM Serendipitous Survey with the Third Reference Catalogue of Bright Galaxies.2011MNRAS.416.1844Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/416/1844CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/155 : RC3 (de Vaucouleurs+ 1991)IX/40 : The XMM-Newton 2nd Incremental Source Catalogue (2XMMi)IX/41 : XMM-Newton Serendipitous Source Catalogue 2XMMi-DR3J/A+A/493/339 : XMM-Newton serendipitous Survey.
