Hierarchical clustering and the baryon distribution in galaxy clusters
Abstract
The baryon fraction of galaxy clusters in numerical simulations is found to be dependent on the cluster formation method. In all cases, the gas is antibiased compared with the dark matter. However, clusters formed hierarchically are found to be more depleted in baryons than clusters formed non-hierarchically. There is a depletion of 10 to 15 per cent for hierarchically formed clusters, while the depletion is less than 10 per cent for those …
