Hi everyone, Inoue & Nagashima have a paper http://de.arXiv.org/abs/astro-ph/0110503 about the mass function of dark matter haloes, in other words, the frequency of how many objects of different masses (high or low) form at a given epoch during the collapse of matter due to gravity. I think this could be an important paper for modelling what statistical constraints on Omega_m & Omega_Lambda (or eventually w_Q) could be obtained from OCRA. Boud
