(Classification of X-ray Sources for Novices)

CLAXSON is a platform designed to identify new objects observed in the X-ray sky with the European Space Agency X-ray telescope XMM-Newton. Be the first to find new supermassive black holes, stars, galaxies and other exotic objects in observations taken over the last 20 years, and help astronomers unravel the mysteries of the X-ray sky.
