Baryon fractions in clusters of galaxies: evidence against a preheating model for entropy generation

Abstract

TheMillenniumGas Project aims to undertake smoothed particle hydrodynamic resimulations of themillennium simulation, providingmany hundredmassive galaxy clusters for comparison with X-ray surveys (170 clusters with kTsl > 3 keV). This paper looks at the hot gas and stellar fractions of clusters in simulations with different physical heating mechanisms… (More)
