Schlegel, David ; Davis, Marc ; Summers, Frank ; Holtzman, Jon A. Abstract The local galaxy distribution offers an interesting constraint to cosmological models of structure formation. The galaxies are distributed in a long, filamentary structure, presumably the result of large amplitude gravitational instability, yet the local velocity field is cold. In particular, there are no blueshifted galaxies within 5h^-1^ Mpc except those within the Local Group radius of 1h^-1^ Mpc. Using numerical simulations we demonstrate that such a situation is extremely rare for an observer in {OMEGA} = 1 CDM models, but is not uncommon in mixed dark matter models that include massive neutrinos.
