Analysis of the Amplitude of the Sunyaev-Zel'dovich Effect out to
  Redshift z=0.8
  The interaction of the cosmic microwave background (CMB) with the hot gas in
clusters of galaxies, the so-called Sunyaev--Zel'dovich (SZ) effect, is a very
useful tool that allows us to determine the physical conditions in such
clusters and fundamental parameters of the cosmological models. In this work,
we determine the dependence of the the SZ surface brightness amplitude with
redshift and mass of the clusters. We have used PLANCK+IRAS data in the
microwave-far infrared and a catalog with >10^5 clusters of galaxies extracted
from the SDSS by Wen et al. (2012). We estimate and subtract the dust emission
from those clusters. From the residual flux, we extract its SZ flux densities.
  The absolute value of the SZ amplitude indicates that the gas mass is around
10% of the total mass for cluster masses of M~10^{14} M_sun. This amplitude is
compatible with no evolution with redshift and proportional to M^{2.70+/-0.37}
(using X-ray derived masses) or M^{2.51+/-0.38} (using weak-lensing derived
masses), with some tension regarding the expectations of the self-similar
dependence (amplitude proportional to M^{5/3}).
  Other secondary products of our analysis include that clusters have a dust
emission with emissivity index beta~2 and temperature T~25 K; we confirm that
the CMB temperature agrees with a dependence of T_0(1+z) with clusters of much
lower mass than those explored previously; and we find that the cluster masses
derived by Wen et al. (2012) from a richness-mass relationship are biased by a
factor of (1+z)^{-1.8} with respect to the X-ray and weak-lensing measurements.
