Results from the SuperModel Analysis of the X-COP Galaxy Clusters Sample
  In this work, the analysis of the stacked projected temperature profile of
twelve galaxy clusters of the X-COP sample is performed via the SuperModel, a
tool for investigating the intracluster medium thermodynamic properties already
tested on many clusters since 2009. Two separate fits have been carried out: to
the joint X-ray and SZ projected temperature profiles and to the X-ray data
only. The entropy, thermal pressure and hydrostatic mass profiles of the
cluster sample and the level of the nonthermal pressure component in the
cluster outskirts are determined combining the deprojected temperature profile
with the stacked electron gas density profile corrected for clumpiness. The
first analysis gives results in good agreement with those reported in
Ghirardini et al. (2018): a modest presence of the nonthermal support and an
entropy profile that follows at distances beyond r500 the predicted power law
increase with slope 1.1. On the contrary, the results of the second analysis
are consistent with the findings obtained by the Suzaku observations, steep
temperature and flat entropy profiles, with a higher level of the nonthermal
pressure component in agreement with the values derived by numerical
simulations. The conclusion is that a steep temperature profile could be
present in the outskirts of the X-COP cluster sample instead of the flatter
temperature profile reported by SZ observations.
