Power density spectrum plot feature added to the website. Its use is showcased in a tutorial where one can re-discover several new extragalactic pulsars — super-Eddington pulsars in ULX and the slowest spinning X-ray pulsar in a globular cluster.

3XMM-DR6 catalog release added to the website. Read more about it here. Note that you can still access legacy catalog releases DR4 and DR5 by choosing displayed catalog version in the settings dialog (wheel icon in the top right corner).

New features of the XMM-Newton photon database. Try photons extraction from an observation of 1E 1547.0-5408, a well-known magnetar, and see its pulsations for yourself. 7000+ XMM-Newton observations and ~50 billion calibrated and barycentered photons are accessible from this website.

This website provides experimental access to the XMM-Newton source catalog 3XMM-DR6 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 9160 XMM-Newton observations that took place between 2000 and mid 2015 covering 2.4% of the sky and compiled present catalog. It comprises 678,680 individual detections of 468,440 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

Please note that this website is in its early beta stage. Feel free to report the issues and vote for requested features at dedicated user feedback page. If you find this website useful for your research, please include its URL and the reference to Zolotukhin et al. (2017) ApJ 839 125 in your publications.
