Abstract

We present results of including heating and cooling in cosmological simulations of the ΛCDM cosmology and demonstrate their effects on scaling laws of galaxy clusters. The scaling relations when radiative cooling is included are in good agreement with observations but the fraction of cooled gas is on the upper limit allowed by observations. On the contrary, the preheating model has a more realistic cooled fraction but the scaling relations are less well produced.
