Figure 2: A slice of the density field of the ψDM simulation on various scales at z = 0.1.

This scaled sequence (each of thickness 60 pc) shows how quantum interference patterns can be clearly seen everywhere from the large-scale filaments, tangential fringes near the virial boundaries, to the granular structure inside the haloes. Distinct solitonic cores with radii ∼0.3–1.6 kpc are found within collapsed haloes (which have virial masses M_vir ∼ 10⁹–10¹¹ M_⊙). The density shown here spans over nine orders of magnitude, from 10⁻¹ to 10⁸ (normalized to the cosmic mean density). The colour map scales logarithmically, with cyan corresponding to density ≲10.
