Reason for selection:

First pictures obtained from an AIP-NMSU super-computing project on the most powerful computer in Europe.


Detail of a 25 Mpc simulation (using the MMART code - multiple-mass adaptive refinement tree) at redshift 0.25: This group contains three massive halos and 110 smaller satellites (zoom into the left, middle, right of the three massive halos). The progenitor of this object at redshift one shows two of the massive halos in the progress of merging. At redshift 5.5 a huge number of small halos can be seen along filaments.
