2 The rates and modes of gas accretion onto galaxies and their gaseous haloes We study the rate at which gas accretes onto galaxies and haloes and investigate whether the accreted gas was shocked to high temperatures bef

4 Properties of gas in and around galaxy haloes We study the properties of gas inside and around galaxy haloes as a function of radius and halo mass, focusing mostly on z = 2, but also showing some results for z = 0. For

1 Introduction Galaxy formation has undergone fast development in the past few decades, both theoretically and observationally. The number of observed galaxies is expanding rapidly and observations are pushing to lower m
