Fig. 1.

Three-dimensional correlation and related functions of LCDM models for different particle density threshold δ₀ limits. Left panel: CF. Central panel: gradient function, γ(r) = dlog g(r)/dlog r. Right panel: bias function, , using the CF of the full DM LCDM.00 model as a reference. As argument we use the pair separation in 3D real space, .
