These six panels show the spatial distribution of galaxies (black dots) and dark matter (color-coded maps) in the constrained simulations of the Great Wall region (GW, top two panels), the Coma cluster region (CM, middle two panels), and the low-density void region (LD, bottom two panels) in the J2000.0 R.A. and decl.. Note that the upper panel of GW and the left panels of CM and LD show real galaxies from the SDSS galaxy redshift survey.
