The dynamics of satellite disruption in cold dark matter haloes
numerical N-body simulation
2014/12/22
We investigate the physical mechanisms of tidal heating and satellite disruption in cold dark matter host haloes using N-body simulations based on cosmological initial conditions. We show the importan...
Using Dark Matter Haloes to Learn about Cosmic Acceleration: A New Proposal for a Universal Mass Function
Dark Matter Haloes Cosmic Acceleration
2011/1/11
Structure formation provides a strong test of any cosmic acceleration model because a successful dark energy model must not inhibit {\black or overpredict} the development of observed large-scale stru...

We use two cosmological simulations of structure formation to study the condi-tions under which dark matter haloes emerge from the linear density field. Our analysis focuses on matching sites of halo ...
Bound and unbound substructures in Galaxy-scale Dark Matter haloes
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We analyse the coarse-grained phase-space structure of the six Galaxy-scale dark matter haloes of the Aquarius Project using a state-of-the-art 6D substructure finder. Within r_50, we find that about ...
DARK MATTER HALOES：AN ADDITIONAL CRITERION FOR THE CHOICE OF FITTING DENSITY PROFILES
cosmology dark matter
2009/3/5
Simulated dark matter haloes are tted by self-similar, universal
density pro les, where the scaled parameters depend only on a scaled (truncation)
radius, = R=r0, which, in turn, is supposed to b...
