Description
We investigate the orientation of the axes and angular momentum of dark
matter halos with respect to their neighboring voids using
high-resolution N-body cosmological simulations. We find that the minor
axis of a halo tends to be aligned along the line joining the halo with
the center of the void and that the major axis tends to lie in the plane
perpendicular to this line. However, we find that the angular momentum
of a halo does not have any particular orientation. These results may
provide information about the mechanisms whereby the large-scale
structure of the universe affects galaxy formation, and they may cast
light on the issue of the orientation of galaxy disks with respect to
their host halos.
