Pressure profiles of distant Galaxy clusters with Planck-SPT data
  We present a full set of numerical tools to extract Galaxy Cluster pressure
profiles from the joint analysis of Planck and South Pole Telescope (SPT)
observations. Pressure profiles are powerful tracers of the thermodynamic
properties and the internal structure of the clusters. Tracing the pressure
over the cosmic times allows to constraints the evolution of the cluster
structure and the contribution of astrophysical phenomena. SPT and Planck are
complementary to constrain the cluster structure at various spatial scales. The
SPT cluster catalogue counts 677 cluster candidates up to redshift 1.7, it is a
nearly mass limited sample, an ideal benchmark to test cluster evolution. We
developed a pipeline to first separate the cluster signal from the background
and foreground components and then jointly fit a parametric profile model on a
combination of Planck and SPT data. We validate our algorithm on a sub-sample
of six clusters, common to the SPT and the CHEX-MATE catalogues, comparing the
results with the profiles obtained from X-ray observations with XMM-Newton.
