New Catalog of the X-Ray Sky
August 19, 2013
The XMM-Newton X-ray telescope was launched in December 1999 and has been obtaining deep, sensitive pictures of X-ray emitting sources in space ever since. Using the powerful ALICE supercomputer, scientists at the XMM-Newton Survey Science Centre have examined every XMM image and have painstakingly catalogued each and every X-ray source detected by XMM-Newton. This catalog, called the “3XMM Catalog”, contains over a half million X-ray sources, including over 370,000 unique sources. Two SESDA staff members helped create the catalog.
