Testing for evolution in scaling relations of galaxy clusters: Cross
  analysis between X-ray and SZ observations
  We present predicted Sunyaev-Zeldovich (SZ) properties of known X-ray
clusters of galaxies for which gas temperature measurements are available. The
reference sample was compiled from the BAX database for X-ray clusters. The
Sunyaev-Zeldovich signal is predicted according to two different scaling laws
for the mass-temperature relation in clusters: a standard relation and an
evolving relation that reproduces well the evolution of the X-ray temperature
distribution function in a concordance cosmology. Using a Markov Chain Mote
Carlo (MCMC) analysis we examine the values of the recovered parameters and
their uncertainties. The evolving case can be clearly distinguished from the
non-evolving case, showing that SZ measurements will indeed be efficient in
constraining the thermal history of the intra-cluster gas. However, significant
bias appears in the measured values of the evolution parameter for high SZ
threshold owing to selection effects.
