Anisotropic Secondary Bias of Dark Matter Haloes in a $Λ$CDM Universe

Secondary bias is the dependence of halo clustering on properties beyond halo mass.

Secondary bias is the dependence of halo clustering on properties beyond halo mass. Using the $z=0$ TNG300-1-Dark simulation, we study anisotropic secondary bias (ASB): the variation of secondary bias with direction relative to the halo major axis. We first use ordinary,…
