WEBSITE OVERVIEW

This website provides experimental access to the XMM-Newton source catalog 4XMM-DR11 and some of its associated data products. Launched in 1999, the XMM-Newton satellite is the major European X-ray observatory-class telescope that is operated by the European Space Agency (ESA). The XMM-Newton Survey Science Centre has run the pipeline that processed data of 12210 XMM-Newton observations that took place between 2000 and 2020 covering 1239 square degrees of the sky and compiled present catalog. It comprises 895 415 individual detections of 602 543 unique X-ray sources and so far it is the largest existing X-ray catalog.

Here you can:

  • search the sources table
  • explore data on individual detections of sources you selected
  • fit X-ray spectra of detections
  • download any associated data products for own analysis
  • plot search results
  • build Virtual Observatory workflows to study lists of sources
