Ahf: Amiga's Halo Finder
Cosmological simulations are the key tool for investigating the different processes involved in the formation of the universe from small initial density perturbations to galaxies and clusters ofExpand
A mass-dependent density profile for dark matter haloes including the influence of galaxy formation
ABSTRACT We introduce a mass dependent density profile to describe the distribution of dark matterwithin galaxies, which takes into account the stellar-to-halo mass dependence of the responseof darkExpand
The dependence of dark matter profiles on the stellar-to-halo mass ratio: a prediction for cusps versus cores
We use a suite of 31 simulated galaxies drawn from the MaGICC project to investigate the effects of baryonic feedback on the density profiles of dark matter haloes. The sample covers a wide massExpand
The evolution of substructure - III. The outskirts of clusters
We present an investigation of satellite galaxies in the outskirts of galaxy clusters taken from a series of high-resolution N-body simulations. We focus on the so-called backsplash population, i.e.Expand
The halo mass function through the cosmic ages
In this paper we investigate how the halo mass function evolves with redshift, based on a suite of very large (with N_p = 3072^3 - 6000^3 particles) cosmological N-body simulations. Our haloExpand
The evolution of substructure - I. A new identification method
We describe our new 'MLAPM halo finder' (MHF), which is based on the adaptive grid structure of the N-body code MLAPM. We then extend the MHF code in order to track the orbital evolution ofExpand
Haloes gone MAD: The Halo-Finder Comparison Project
We present a detailed comparison of fundamental dark matter halo properties retrieved by a substantial number of different halo finders. These codes span a wide range of techniques includingExpand
Internal Alignment of the Halos of Disk Galaxies in Cosmological Hydrodynamic Simulations
Seven cosmological hydrodynamic simulations of disk galaxy formation are analyzed to determine the alignment of the disk within the dark matter halo and the internal structure of the halo. We findExpand
The evolution of substructure – II. Linking dynamics to environment
We present results from a series of high-resolution N-body simulations that focus on the formation and evolution of eight dark matter haloes, each of the order of a million particles within theExpand
On the Correlation between Spin Parameter and Halo Mass
We report on a correlation between virial mass M and spin parameter λ for dark matter halos forming at redshifts z 10. We find that the spin parameter decreases with increasing halo mass.Expand
