Formation of larger galaxies and clusters clearly have to involve significant phase space dilution, probably because of mergers [4].

This is equivalent to the mixing-theorem construction of the maximal coarse-grained phase space density discussed in S. Tremaine, M. Hénon, and D. Lynden-Bell, Mon. Not. R. Astron. Soc. 219, 285 (1986) (in the following THL); see also

THL demonstrated that there exists a maximal possible fraction of particles F((ø) from a given fine-grained distribution that can evolve dissipationlessly to have a coarse-grained occupation number higher than a given value ø. This function F(ø) is obtained by packing the fine-grained distribution f(p) using the densest cells (highest f) first. For a kinetic equilibrium distribution, where/(p) is a decreasing function of p, the THL construction is equivalent to the momentum cut construction in the present paper. Whereas an actual galaxy formation process may not utilize phase space fully in this optimal way, something close to this would be expected if the process naturally picks low-momentum particles only (as would be the case for dwarf galaxies). There is also evidence from numerical simulations of massive neutrinos that phase space may be surprisingly well utilized on larger scales, cf. A. L. Melott, Phys. Rev. Lett. 48, 894 (1982);
