The XMM-Newton Survey Science Catalogues

The XMM-Newton Survey Science Centre produces catalogues of all X-ray sources detected with XMM-Newton. All catalogues up to 3XMM-DR4 were produced by the University of Leicester in collaboration with the other SSC institutes. Links to all the catalogues can be found on these pages. Ulterior catalogues are produced at the Institut de Recherche en Astrophysique et Planétologie in Toulouse, in collaboration with the other SSC institutes and the XMM-Newton Science Operations Centre (SOC). Catalogues based on a reprocessing of all the data used are named 1XMM, 2XMM, 3XMM, etc. Incremental versions of these catalogues are also released on a regular basis and these include data that has become public since the release of the previous catalogue and processed with a similar, but not necessarily identical, version of the SAS. All information concerning the data reduction steps can be found on the web pages provided for each catalogue version. Complimentary information are provided in the 2XMM paper (The XMM-Newton serendipitous survey. V. The Second XMM-Newton serendipitous source catalogue Watson et al. (2009)) and the 3XMM paper. Should you use the catalogue for your research and publish the results, please use the acknowledgement below and cite the paper describing the catalogue (Rosen, Webb, Watson et al., 2016, A&A, 590, 1). .

This research has made use of data obtained from the 3XMM XMM-Newton serendipitous source catalogue compiled by the 10 institutes of the XMM-Newton Survey Science Centre selected by ESA.

The catalogue can also be queried at:

We also provide a stacked catalogue of sources, 3XMM-DR7s released with 71951 stacked X-ray sources, the first catalogue of XMM-Newton X-ray sources from regions of the sky observed repeatedly.

It is also browsable via the web-based interfaces

The XSA provides access to the auxiliary data products per source: a broad-band X-ray image, a colour-coded three-band X-ray image, an optical finding chart, and a long-term X-ray light curve.

Should you have any issues that you wish to raise concerning the X-ray catalogue, please send an email to Natalie Webb with the title '3XMM catalogue issues'.

We also propose a spectral-fit database that proposes simple spectral fits for 146825 detections (99356 sources) in the 3XMM-DR6. Access to the information describing the catalogue can be found on the XMM-Newton spectral-fit database webpage and the database is held here (3XMMSPECTRAL).

We also help produce the XMM-Newton Optical Monitor (OM) Serendipitous Ultra-violet Source Survey Catalogue (XMM-SUSS, Page et al. (2012)). The latest version, XMM-SUSS4.1 contains 8.17 million detections (5.5 million unique sources). It can be queried at:
