Mass accretion history of the haloes, computed as the mass of dark matter enclosed within r <  R_200, z at redshift z, normalised by the mass at z = 0, as a function of redshift for SPH (filled lines, Aq-A-SPH red, Aq-C-SPH brown, Aq-D-SPH green, and Aq-E-SPH blue) and DMO (dashed lines) counterparts. We also include the results from Aq-C-M14 (grey solid line). We compare our results with Eq. (2) from Fakhouri et al. (2010; black line). The grey horizontal line is used as reference to estimate the formation time of the haloes, as the redshift at which the mass of the halo reach half of their mass at z = 0.
