Ratio between either the hydrodynamic mass (top panels) or the reconstructed virial mass (bottom panels) and the dmo counterpart on the subset of Magneticum Boxes 1a for the simulations with different cosmologies (see Table 2). Different columns correspond to the four redshifts z ∈ {0.0, 0.3, 0.5, 0.9} and different colours correspond to different cosmic baryon fractions f_b. The filled dark-grey and light-grey areas mark the 1 and 2 percent halo mass variation induced by baryonic effects, respectively.
