Hot and cooled baryons in smoothed particle hydrodynamic simulations of galaxy clusters: physics and numerics
Hot and cooled baryons in smoothed particle hydrodynamic simulations of galaxy clusters: physics and numerics
We discuss an extended set of Tree+SPH simulations of galaxy clusters, with the goal of investigating the interplay between numerical resolution effects and star-formation/feedback processes. The simulated clusters span the mass range (0.1-2.3) 10^{15}Msun/h, with mass resolution varying by several decades. At the highest achieved resolution, we resolve the virial …
