Euclid Definition Study Report
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to investigate theExpand

The mass function and average mass-loss rate of dark matter subhaloes
We present a simple, semi-analytical model to compute the mass functions of dark matter subhaloes. The masses of subhaloes at their time of accretion are obtained from a standard merger tree. DuringExpand

The population of dark matter subhaloes: mass functions and average mass-loss rates
Using a cosmological N-body simulation and a sample of resimulated cluster-like haloes, we study the mass-loss rates of dark matter subhaloes, and interpret the mass function of subhaloes at redshiftExpand

Lensing and x-ray mass estimates of clusters (simulations)
We present a comparison between weak-lensing and x-ray mass estimates of a sample of numerically simulated clusters. The sample consists of the 20 most massive objects at redshift z = 0.25 and M_virExpand

The universality of the virial halo mass function and models for non-universality of other halo definitions
The abundance of galaxy clusters can constrain both the geometry and growth of structure in our Universe. However, this probe could be significantly complicated by recent claims ofExpand

The MUSIC of CLASH: Predictions on the Concentration-Mass Relation
We present an analysis of the MUSIC-2 N-body/hydrodynamical simulations aimed at estimating the expected concentration-mass relation for the CLASH (Cluster Lensing and Supernova Survey with Hubble)Expand

The substructure hierarchy in dark matter haloes
We present a new algorithm for identifying the substructure within simulated dark matter haloes. The method is an extension of that proposed by Tormen, Moscardini & Yoshida and Giocoli, Tormen & vanExpand

An improved model for the formation times of dark matter haloes
A dark matter halo is said to have formed when at least half its mass has been assembled into a single progenitor. With this definition, it is possible to derive a simple but useful analytic estimateExpand

We present measurements of the small-scale (0.1 ≲ r ≲ 1 h^(-1) Mpc) quasar two-point correlation function at z>2.9, for a flux-limited (i < 21) sample of 15 binary quasars compiled by Hennawi et al.Expand

Formation times, mass growth histories and concentrations of dark matter haloes
We develop a simple model for estimating the mass growth histories of dark matter halos. The model is based on a t to the formation time distribution, where formation is dened as the earliest timeExpand
