We study the effects of radiative cooling, star formation and stellar feedback on the properties and evolution of galaxy clusters using high-resolution Adaptive Mesh Refinement N-body+gasdynamics simulations of clusters forming in the $\Lambda$CDM universe. Cooling leads to the condensation of gas in the inner regions of clusters, which in turn leads to steepening of the dark matter profile. The cooling gas is replaced by the higher-entropy gas from the outer regions, which raises the entropy… 
nIFTy galaxy cluster simulations – II. Radiative models
We have simulated the formation of a massive galaxy cluster (M$_{200}^{\rm crit}$ = 1.1$\times$10$^{15}h^{-1}M_{\odot}$) in a $\Lambda$CDM universe using 10 different codes (RAMSES, 2 incarnations of
Recent studies suggest that active galactic nuclei and cosmic rays drive convection in galaxy-cluster plasmas and that convection heats cluster cores and regulates the plasma temperature profile. In
AGN-driven Convection in Galaxy-Cluster Plasmas
This paper describes how active galactic nuclei can heat galaxy-cluster plasmas by driving convection in the intracluster medium. A model is proposed in which a central supermassive black hole
Convection and AGN Feedback in Clusters of Galaxies
A number of studies have shown that the convective stability criterion for the intracluster medium (ICM) is very
