Journal ArticleDOI
Spatial distribution of galactic halos and their merger histories
Stefan Gottloeber,Martin Kerscher,Andrey V. Kravtsov,Andreas Faltenbacher,Anatoly Klypin,Volker Mueller +5 more
TL;DR: In this article, mark correlation functions (MCFs) were used to study clustering of galaxy-size halos as a function of their properties and environment in a high-resolution numerical simulation of the LambdaCDM cosmology.
Journal ArticleDOI
Testing Gravity With Motion of Satellites Around Galaxies: Newtonian Gravity Against Modified Newtonian Dynamics
Anatoly Klypin,Francisco Prada +1 more
TL;DR: In this paper, the surface density and velocities of satellites around isolated red galaxies in the Sloan Digital Sky Survey were studied, and it was shown that the surface number density of satellites declines with the projected distance as a power law with the slope −1.5 to 2.60.

Testing gravity with motion of satellites around galaxies: Newtonian gravity against Modified Newtonian Dynamics
Anatoly Klypin,Francisco Prada +1 more
TL;DR: In this article, the authors study the surface density and velocities of satellites around isolated galaxies in the Sloan Digital Sky Survey and find that the surface number-density of satellites declines with the projected distance as a power law with the slope -1.5-2.
Journal ArticleDOI
A universal angular momentum profile for galactic halos
James S. Bullock,Avishai Dekel,Tsafrir S. Kolatt,Andrey V. Kravtsov,Anatoly Klypin,Cristiano Porciani,Joel R. Primack +6 more
TL;DR: In this paper, the authors studied the angular-momentum profiles of a statistical sample of halos drawn from a high-resolution N-body simulation of the LCDM cosmology, and found that the cumulative mass distribution of specific angular momentum, j, in a halo of mass Mv is well fit by a universal function, Mv = Mv \mu j/(j_0+j).
Journal ArticleDOI
Phase-space structure of dark matter haloes: scale-invariant probability density function driven by substructure
TL;DR: In this paper, the authors present a method for computing the six-dimensional coarse-grained phase-space density f(x, v) in an N-body system, and derive its distribution function v(f).
