Using a series of high-resolution N-body simulations of the concordance cosmology we investigate how the formation histories, shapes and angular momenta of dark-matter haloes depend on environment. We first present a classification scheme that allows to distinguish between haloes in clusters, filaments, sheets and voids in the large-scale distribution of matter. This method (which goes beyond a simple measure of the local density) is based on a local-stability criterion for the orbits of test… 


Clusters, filaments, sheets, and voids are the building blocks of the cosmic web. Forming dark matter halos respond to these different large-scale environments, and this in turn affects the

Assembly bias in the clustering of dark matter haloes

We use a very large simulation of structure growth in a Λ cold dark matter (ΛCDM) universe – the Millennium Simulation – to study assembly bias, the fact that the large-scale clustering of haloes of

Impact of Cosmic Filaments on the Gas Accretion Rate of Dark Matter Halos

We investigate the impact of cosmic filaments on the gas accretion rate, Ṁgas , of dark matter halos in filaments, based on cosmological hydrodynamic simulation. We find that for halos less massive

The geometry of the filamentary environment of galaxy clusters

We construct a filament catalogue using an extension of the halo-based filament finder of Zhang et al. (2009), in a 250 Mpc h−1 side N-body simulation, and study the properties of filaments ending


We use N-body simulations to investigate the evolution of the orientation and magnitude of dark matter halo angular momentum within the large-scale structure since z = 3. We look at the evolution of

Internal properties and environments of dark matter haloes

We use seven high-resolution N-body simulations to study the correlations among different halo properties (assembly time, spin, shape and substructure), and how these halo properties are correlated

The Cosmic Ballet: spin and shape alignments of haloes in the cosmic web

We investigate the alignment of haloes with the filaments of the cosmic web using an un-precedently large sample of dark matter haloes taken from the P-Millennium Lambda cold dark matter cosmological

Dependence of the dynamical properties of light-cone simulation dark matter halos on their environment

Aims. We study the dependence of the dynamical properties of massive (M ≥ 1.5 × 1013 M⊙ h−1) dark matter halos on their environment in a whole-sky ΛCDM light-cone simulation extending to z ∼ 0.65.

The shape of dark matter haloes in the Aquarius simulations: evolution and memory

We use the high resolution cosmological N-body simulations from the Aquarius project to investigate in detail the mechanisms that determine the shape of Milky Way-type dark matter haloes. We find

The impact of filamentary accretion of subhaloes on the shape and orientation of haloes

Dark matter haloes are formed through hierarchical mergers of smaller haloes in large-scale cosmic environments, and thus anisotropic subhalo accretion through cosmic filaments has some impacts on



The Dependence on Environment of Cold Dark Matter Halo Properties

A series of high-resolution ΛCDM cosmological N-body simulations are used to study the properties of galaxy-size dark halos as a function of global environment. We analyze halos in three types of

Environmental influences on dark matter haloes and consequences for the galaxies within them

We use large N-body simulations of dissipationless gravitational clustering in cold dark matter (CDM) cosmologies to study whether the properties of dark matter halos are affected by their

The age dependence of halo clustering

We use a very large simulation of the concordance Λ cold dark matter cosmogony to study the clustering of dark matter haloes. For haloes less massive than about 1013 h−1 M⊙ the amplitude of the

The mass function of dark matter haloes

We combine data from a number of N-body simulations to predict the abundance of dark haloes in cold dark matter (CDM) universes over more than four orders of magnitude in mass. A comparison of

A marked correlation function analysis of halo formation times in the Millennium Simulation

We study the environmental dependence of the formation epoch of dark matter haloes in the Millennium Simulation: a ten billion particle N-body simulation of standard Lambda cold dark matter

On the environmental dependence of halo formation

ABSTRACT A generic prediction of hierarchical gravitationalclustering models is that the distribu-tion of halo formation times should depend relatively strongly on halo mass, massivehaloes forming

The Alignment of Dark Matter Halos with the Cosmic Web

We investigate the orientation of the axes and angular momentum of dark matter halos with respect to their neighboring voids using high-resolution N-body cosmological simulations. We find that the

Using six high-resolution dissipationless simulations with a varying box size in a flat Lambda cold dark matter (ACDM) universe, we study the mass and redshift dependence of dark matter halo shapes

Dark halos formed via dissipationless collapse. I: Shapes and alignment of angular momentum

We use N-body simulations on highly parallel supercomputers to study the structure of Galactic dark matter halos. The systems form by gravitational collapse from scale-free and more general Gaussian

The influence of large-scale structures on halo shapes and alignments

Alignments of galaxy clusters (the Binggeli effect), as well as of galaxies themselves have long been studied both observationally and theoretically. Here, we test the influence of large-scale
