Environmental statistics provide a necessary means of comparing the properties of galaxies in different environments and a vital test of models of galaxy formation within the prevailing, hierarchical ...
N-body Simulations for f(R) Gravity using a Self-adaptive Particle-Mesh Code
N-body Simulations Self-adaptive Particle-Mesh Code

2010/11/11
We perform high resolution N-body simulations for f(R) gravity based on a self-adaptive particle-mesh code MLAPM. The Chameleon mechanism that recovers General Relativity on small scales is fully take...
Direct N-body simulations of globular clusters: (I) Palomar 14

We present the first ever direct $N$-body computations of an old Milky Way globular cluster over its entire life time on a star-by-star basis. Using recent GPU hardware at Bonn University, we have per...

Large-scale clustering of highly biased tracers of large-scale structure has emerged as one of the best observational probes of primordial non-Gaussianity of the local type (i.e. f_{NL}^{local}).
Statistical mechanics of collisionless orbits. III. Comparison with N-body simulations

We compare the DARKexp differential energy distribution, N(E) \propto \exp(\phi_0-E)-1, obtained from statistical mechanical considerations, to the results of N-body simulations of dark matter halos.
