We revisit the scaling relationships between the dark matter mass and observed X– ray luminosity and temperature of galaxy clusters and groups in the local Universe. Specifically, we compare recent observations with analytic models of the intracluster medium in which the gas entropy distribution has been shifted by a variable amount, K◦, to investigate the origin of the scatter in these scaling relations, and its influence on the luminosity and temperature functions. We find that variations in… CONTINUE READING
