The total smooth baryonic accretion onto the galaxy. The colour shading shows the total baryonic accretion rate (free-fall coming from filaments and cooling flows) from our reference model, as a function of dark-matter halo mass, and for a set of redshifts. The colour scale indicates the normalised logarithmic density of objects. We add for information the transition mass (10^11.4 M_⊙, grey vertical arrow) used in the accretion mode repartition (Eq. (14)). The dotted and solid black lines show the average baryonic accretion rate deduced from hydrodynamic simulations by Fakhouri et al. (2010) and Ceverino et al. (2010), respectively. Black circles are for a model with photoionisation prescription by Gnedin (2000) instead of our Okamoto et al. (2008) standard prescription. Grey squares show the accretion for a model without any photoionisation process.
