Abstract
The hierarchical nature of halo formation in the Cold Dark Matter (CDM) model
suggests that there should be mass dependent trends in the radial velocity and
velocity anisotropy profiles of dark matter haloes, with more massive systems
exhibiting the effects of more pronounced infall. We present results from a
sample of high resolution cosmological
N-body simulations of individual dwarf,
galaxy and cluster mass haloes, and demonstrate that such trends with mass are
indeed observed.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link containsarticle metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means:
- if your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages,
- you can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library,
- you can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
