“…Fermion stars such as white dwarfs and neutron stars also possess a maximum mass due to special or general relativity. The study of DM halos made of fermions (like sterile neutrinos) is also of interest and can be investigated with methods similar to those exposed in this paper (see, e.g., [264,265,322,323,354] for the development of the analogy between bosonic and fermionic DM).…”

“…In general, ρ m = ρ except (i) for a noninteracting SF (V = 0), (ii) when V is constant, corresponding to the ΛFDM model (see Appendix E of [359]), (iii) and in the nonrelativistic limit c → +∞. Remark: More general results valid beyond the TF approximation are given in [87,360].…”

“…This conclusion is not restricted to the GCG model but is actually valid for all UDM models 8 . Some solutions to this problem have been suggested (see a short review in Section XVI of [116]) but there is no definite consensus at the present time. However, in a recent paper, Abdullah et al [117] argued that a cosmological scenario based on the Chaplygin gas may not be ruled out from the viewpoint of structure formation as usually claimed.…”

“…This is the basic idea that led us to introduce the logotropic model in Ref. [118] (see also [116,[119][120][121][122]). The logotropic dark fluid has an equation of state…”
