The shape of the invisible halo: N‐body simulations on parallel supercomputers
We study the shapes of halos and the relationship to their angular momentum content by
means of N‐body (N∼ 106) simulations. Results indicate that in relaxed halos with no
apparent substructure: i.) The shape and orientation of the isodensity contours tends to
persist throughout the virialized portion of the halo. ii.) Most (≊ 70%) of the halos are prolate.
iii.) The approximate direction of the angular momentum vector tends to persist throughout
the halo. iv.) For spherical shells centered on the core of the halo the magnitude of the …
