Fig. 7.

Spherical slices of thickness ∼2.6 h−1 Mpc through a data constrained realization of the three-dimensional initial (left panel) and final density field (right panel) at a distance of R = 100 h−1 Mpc from the observer. Initial density fields correspond to the epoch of a cosmic scale factor a = 0.001 while non-linear final density fields are evaluated at the present epoch (a = 1). One can see the correspondence of large scale over-densities in the initial conditions and corresponding structures in the gravitationally evolved density field. Red dots in the right panel denote the observed galaxies in the 2M++ survey. As can be seen observed galaxies trace the inferred dark matter distribution.
