[147.05] The X-Ray Temperature, Luminosity and Mass Correlation from XMM-Newton Observations of Distant Galaxy Clusters

O. Kotov, A. Vikhlinin (Harvard-Smithsonian Center for Astrophysics)

We present correlations between X-ray temperature, luminosity and mass for a sample of distant clusters with z \geq 0.394 observed with \emph{XMM-Newton} observatory. Fixing the slope in the L - T correlation at the local value ,\alpha=2.64, we derived that the correlation scales as L \propto (1+z)^{1.7 \pm 0.3} T^\alpha with z, which confirms that the L - T relation evolves with redshift. Making use of the temperature profiles we calibrated the M-T correlation. The resulting M - T correlation in the 2.0-10.0 keV energy band agrees with the self-similar prediction E(z)M \propto T^3/2. The corrected for E(z) normalization is consistent well with the one derived by Vikhlinin et. al. 2004 for local clusters.
