RIXOS Galaxy Cluster
Histogram
Redshift distribution for complete samples
of faint X-ray selected clusters from the RIXOS survey. The dotted datum
represents a candidate cluster with an assigned redshift of z=1.0. Smooth
curves show the predicted redshift distributions for several evolutionary
models: (i) a non-evolving cluster population; (ii) a self-similar model
with n=-1.95 spectral index; and (iii) the best-fitting preheated intracluster
medium model (with spectral index parameter n=-1.5). [TIFF]
