Abstract:
The scaling of observable properties of galaxy clusters with mass
evolves with time. Assessing the role of the evolution is crucial to
study the formation and evolution of massive haloes and to avoid
biases in the calibration. We present a general method to infer the
mass and the redshift dependence, and the time-evolving intrinsic
scatter of the mass-observable relations. The procedure
self-calibrates the redshift-dependent completeness function of the
sample. The intrinsic scatter in the mass estimates used to calibrate
the relation is considered too. We apply the method to the scaling of
mass MDelta versus line-of-sight galaxy velocity dispersion
σv, optical richness, X-ray luminosity, LX, and
Sunyaev-Zel'dovich signal. Masses were calibrated with weak lensing
measurements. The measured relations are in good agreement with time
and mass dependences predicted in the self-similar scenario of
structure formation. The lone exception is the LX-MDelta relation,
whose time evolution is negative in agreement with formation scenarios
with additional radiative cooling and uniform preheating at high
redshift. The intrinsic scatter in the sigmav-MDelta relation is
notably small, of the order of 14 per cent. Robust predictions on the
observed properties of the galaxy clusters in the Cluster Lensing And
Supernova survey with Hubble sample are provided as cases of study.
