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...
The Gauge-Invariant Bias of Dark Matter Haloes with Primordial non-Gaussianity
The Gauge-Invariant Dark Matter Haloes
2010/12/27
The non-linear evolution of the halo population is followed by solving the continuity equation under the hypothesis that haloes move by the action of gravity. An exact and general formula for the Eule...
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...
