Comparison between the effective bias from mass-scaled halo catalogs from OpenGADGET3 and PINOCCHIO and the theoretical expectation from Euclid Collaboration: Castro et al. (2024). Different panels show the results for different redshifts corresponding to {0.0, 0.5, 1.0, 2.0}, going clockwise. Different line styles correspond to different minimum mass selections. We omit the result for the M_cut = 3×10¹⁴ h⁻¹ M_⊙ at z = 2 as the measurements are too noisy due to the low statistics.
