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.
