The CLEF-SSH simulation project
  The CLEF-SSH simulation project is an international collaboration, involving the IAS, LATT and the University of Sussex, to produce large hydrodynamic simulations of large-scale structure that implement realistic models of radiative gas cooling and energy feedback. The objective is to use these simulations to study the physics of galaxy clusters and to construct maps of large angular size of the Sunyaev-Zel'dovich (SZ) effect, for the preparation of future experiments. Here we present results from a first run, the CLEF hydrodynamics simulation, which features 2(428)^3 particles of gas and dark matter inside a comoving box with 200 Mpc/h on a side.
