Clusters of galaxies: new results from the CLEF hydrodynamics simulation

Preliminary results are presented from the CLEF hydrodynamics simulation, a large (N = 2 × 4283 particles within a 200 h−1 Mpc comoving box) simulation of the ΛCDM cosmology that includes both radiative cooling and a simple model for galactic feedback. Specifically, we focus on the X-ray properties of the simulated clusters at z = 0 and demonstrate a reasonable level of agreement between simulated and observed cluster scaling relations.
