Scientific paper

X-ray clusters provide valuable constraints on models of galaxy formation as their gas is directly observable. We present a semi-analytic model which is able to fit the observed properties of X-ray clusters, including their gas fractions, X-ray luminosity function, temperature function, mass deposition rate function and luminosity-temperature relation. X-ray clusters are observed not to be self-similar in structure and we discuss critically different ways of breaking the self-similarity. The retention of supernova energy from earlier stages of hierarchical collapse is modelled by changing the gas density profiles of halos. This is shown to have an important effect in regulating star formation in our model galaxies.
