Simulated local galaxy structures.

Density and velocity fields in a slice through the simulated volume. Positions of several known objects are marked: GA - Great Attractor, LS - Local Supercluster, PP - Perseus-Pisces supercluster, Coma - Coma cluster. The thick large arrow corresponds to the velocity of 1000 km/s. The Local Group is at the center (SGX,SGY) = (0,0). The fields are smoothed with a Gaussian 5 Mpc/h filter.
