Abstract:
    We have processed 2774 high galactic observations from the XMM archive
    (as of 2010 May) and extracted a serendipitous catalogue of some 850
    clusters of galaxies based on purely X-ray criteria, following the
    methodology developed for the XMM-Large-Scale Survey. Restricting the
    sample to the highest signal-to-noise ratio objects (347 clusters), we
    perform a cosmological analysis using only the X-ray information. The
    analysis consists in the modelling of the observed colour-magnitude
    [count rate and hardness ratio (CR-HR)] diagram constructed from
    cluster instrumental count rates measured in the [0.5-2], [1-2] and
    [0.5-1] keV bands. A Monte Carlo Markov chain procedure simultaneously
    fits the cosmological parameters, the evolution of the cluster scaling
    laws and the selection effects.
