The XMM-Newton serendipitous survey. VII. The third XMM-Newton serendipitous source catalogue

XMM-Newton is the largest effective-area, focusing X-ray facility. The 3XMM-DR5 catalog presents the latest and largest systematic effort in exploiting the enormous database made by more than 7,500 pointed observations. Almost 400,000 individual sources were detected, and X-ray spectra and light curves were extracted for the brightest 25%. The catalog contains a variety of sources from nearby objects within the solar system to the most massive black holes in the farthest Universe. Most of them still need to be discovered. The catalog is publicly available to the community on the XMM-Newton Survey Science Centre website.
