Discrepancies have emerged between the predictions of standard cold dark matter (CDM) theory and observations of clustering on subgalactic scales. Warm dark matter (WDM) is a simple modification of CDM in which the dark matter particles have initial velocities due either to their having decoupled as thermal relics or to their having been formed via nonequilibrium decay. We investigate the nonlinear gravitational clustering of WDM with a high-resolution N-body code and identify a number of… Expand
Status of cold dark matter cosmology
Abstract Cold Dark Matter (CDM) has become the standard modern theory of cosmological structure formation. Its predictions appear to be in good agreement with data on large scales, and it naturallyExpand
Warm dark haloes accretion histories and their gravitational signatures
We study clusters in Warm Dark Matter (WDM) models of a thermally produced dark matter particle 0:5 keV in mass. We show that, despite clusters in WDM cosmologies having similar density profiles asExpand
The properties of warm dark matter haloes
Well-motivated elementary particle candidates for the dark matter, such as the sterile neutrino, behave as warm dark matter (WDM). For particle masses of order a keV, free streaming produces a cutoffExpand
The warm dark matter halo mass function below the cut-off scale
Warm Dark Matter (WDM) cosmologies are a viable alternative to the Cold Dark Matter (CDM) scenario. Unfortunately, an accurate scrutiny of the WDM predictions with N-body simulations has provenExpand
The first billion years of a warm dark matter universe
We present results of cosmological N-body hydrodynamic chemistry simulations of primordial structure growth and evolution in a scenario with warm dark matter (WDM) having a mass of 3 keV (thermalExpand
The Extended Stellar Component of Galaxies the Nature of Dark Matter
Deep observations of galaxies reveal faint extended stellar components (hereafter ESCs) of streams, shells, and halos. These are a natural prediction of hierarchical galaxy formation, as accretedExpand
Warm Dark Matter and Cosmic Reionization
In models with dark matter made of particles with keV masses, such as a sterile neutrino, small-scale density perturbations are suppressed, delaying the period at which the lowest mass galaxies areExpand
What sets the central structure of dark matter haloes
Dark matter (DM) haloes forming near the thermal cut-off scale of the density perturbations are unique, since they are the smallest objects and form through monolithic gravitational collapse, whileExpand
The inner structure of dwarf sized halos in Warm and Cold Dark Matter cosmologies
By means of N-body+Hydrodynamic zoom-in simulations we study the evolution of the inner dark matter and stellar mass distributions of central dwarf galaxies formed in halos of virial massesExpand
Simulations of galaxies formed in warm dark matter halos of masses at the filtering scale
We present zoom-in N-body + Hydrodynamic simulations of dwarf central galaxies formed in Warm Dark Matter (WDM) halos with masses at present-day of $2-4\times 10^{10}$ \msun. Two different cases areExpand


Formation and Structure of Halos in a Warm Dark Matter Cosmology
Using high-resolution cosmological N-body simulations, we study how the density profiles of dark matter halos are affected by the filtering of the density power spectrum below a given scale lengthExpand
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 ofExpand
The dark matter problem in disc galaxies
In the generic CDM cosmogony, dark-matter haloes emerge too lumpy and centrally concentrated to host observed galactic discs. Moreover, discs are predicted to be smaller than those observed. We argueExpand
Dark Halo and Disk Galaxy Scaling Laws in Hierarchical Universes
We use cosmological N-body/gasdynamical simulations that include star formation and feedback to examine the proposal that scaling laws between the total luminosity, rotation speed, and angularExpand
The Structure of Dark Matter Halos in Hierarchical Clustering Theories
During hierarchical clustering, smaller masses generally collapse earlier than larger masses and so are denser on the average. The core of a small-mass halo could be dense enough to resist disruptionExpand
Dark Matter Substructure within Galactic Halos
We use numerical simulations to examine the substructure within galactic and cluster mass halos that form within a hierarchical universe. Clusters are easily reproduced with a steep mass spectrum ofExpand
Constraints on Warm Dark Matter from Cosmological Reionization
We study the constraints that high-redshift structure formation in the universe places on warm dark matter (WDM) dominated cosmological models. We modify the extended Press-Schechter formalism toExpand
Cold collapse and the core catastrophe
We show that a universe dominated by cold dark matter fails to reproduce the rotation curves of dark matter dominated galaxies, one of the key problems that it was designed to resolve. We performExpand
Hierarchical galaxy formation and substructure in the Galaxy's stellar halo
We develop an explicit model for the formation of the stellar halo from tidally disrupted, accreted dwarf satellites in the cold dark matter (CDM) framework, focusing on predictions testable with theExpand

We reexamine the disk-halo decompositions of the rotation curves of low surface brightness (LSB) galaxies with Vmax ≥ 80 km s-1, taking full account of the effects of beam smearing. We show that theExpand
