VL-2 images :The following images are different versions of Figure 1 in Diemand et al. 2008:
VL-1 images :  z=0   low resolution,z=0   z=0.3   z=0.8  z=2.0   z=3.7  z=6.2   z=10.6  composites   sub-subhalosProjected dark matter density-square maps of the simulated Milky Way-size halo Via Lactea-1 at the various epochs. The logarithmic color scale covers the same 24 decades in projected density-square in physical units in each panel. Most images are 1024x768 pixels (composites are larger) and they are available as full quality PNG version and as smaller, compressed version in JPEG format.
at z=0, i.e. today
low resolution simulation (27 times fewer particles) also at z=0, for comparison
at z=0.31, 3.4 billion years ago
at z=0.82, 6.8 billion years ago
at z=2.0, 10.3 billion years ago, 3.5 billion years after the Big Bang
at z=3.7, 12.0 billion years ago, 1.8 billion years after the Big Bang
at z=6.2, 12.8 billion years ago, 940 million years after the Big Bang
at z=10.6, 13.3 billion years ago, 460 million years after the Big Bang
composite images: same physical volume at six different redshifts
sub-subhalos at z=0
Projected dark matter density-square maps of the four most massive subhalos within the simulated Milky Way host at the present epoch. Sub-substructure is clearly visible. On the left, only dark matter particles within the tidal radius are used for the projections. On the right, dark matter particles within a cube enclosing the tidal radius are used. See astro-ph/0611370 for details.
