hi cosmo-torun,

These two articles may be useful especially for Zbyszek and Bartek:

* n-body review http://arxiv.org/abs/1106.1082v1 Dehnen and Read * correction by Adrian Melott http://arxiv.org/abs/1105.1774

i'm not sure if there's anything especially new in 1106.1082, but figs 5 and 6 look nice, and reading a review paper you can often find something you didn't know before.
