Halo bias in the MTNG-DMO simulation. The halo bias is computed as the ratio of the halo–matter cross-correlation function to the theoretical matter correlation function. The dotted and dashed lines show the biases of the haloes in the lower and upper 20% of the concentration distribution, respectively, in bins of halo mass (i.e. the concentration halo assembly bias). The shaded regions correspond to the bins in m_peak used in this work, which should approximately map onto similar halo-mass ranges.
