First confirmation of anisotropic bias from statistically anisotropic matter distributions

We confirm for the first time the existence of distinctive halo bias associated with the quadrupolar type of statistical anisotropy (SA) of the linear matter density field using cosmological \(N\)-body simulations. We find that the coefficient of the SA-induced bias for cluster-sized halos takes neg...
