The predicted density profiles become flat at small radii, as expected from the effects of the spectrum cut-off. The core cannot be resolved, however, because the non-null particle velocity yields the fragmentation of minimum mass protohaloes in small nodes, which invalidates the model at the corresponding radii.5 p.application/pdfeng(c) Viñas, Jordi et al., 2012Halos (Meteorologia)CosmologiaMatèria fosca (Astronomia)Halos (Meteorology)CosmologyDark matter (Astronomy)info:eu-repo/semantics/article6153612023-02-02info:eu-repo/semantics/openAccess
