Abstract (from CDS):

We derive correlations between X-ray temperature, luminosity, and gas mass for a sample of 22 distant, z>0.4, galaxy clusters observed with Chandra. We detect evolution in all three correlations between z>0.4 and the present epoch. In particular, in the Ω=0.3, Λ=0.7 cosmology, the luminosity corresponding to a fixed temperature scales approximately as (1+z)1.5±0.3; the gas mass for a fixed luminosity scales as (1+z)–1.8±0.4; and the gas mass for a fixed temperature scales as (1+z)–0.5±0.4 (all uncertainties are 90% confidence). We briefly discuss the implication of these results for cluster evolution models.
