We perform ray-tracing simulations evaluating the effect of a cD galaxy on the strong lensing properties of five galaxy cluster haloes obtained from N-body simulations. The cD galaxy is modelled using both axially symmetric and elliptical models and assuming several masses for its dark matter halo. The effect of the cD orientation with respect to the mass distribution of the host galaxy cluster is also investigated. The simulations are carried out in an open and a flat model universe with…

Cluster strong lensing in the Millennium simulation: the effect of galaxies and structures along the line-of-sight
We use ray-tracing through the Millennium simulation to study how secondary matter structures along the line-of-sight and the stellar mass in galaxies affect strong cluster lensing, in particular the
Impacts of Source Properties on Strong Lensing by Rich Galaxy Clusters
We use a high-resolution N-body simulation to investigate the influence of background galaxy properties, including redshift, size, shape, and clustering, on the efficiency of forming giant arcs by
Characterizing strong lensing galaxy clusters using the Millennium-XXL and MOKA simulations
In this paper, we investigate the strong lensing statistics in galaxyclusters. We extract dark matter haloes from the Millennium- XXL simulation, compute their Einstein radius distribution, and find
The effects of ellipticity and substructure on estimates of cluster density profiles based on lensing and kinematics
We address the question of how well the density profile of galaxy clusters can be determined by combining strong lensing and velocity dispersion data. We use cosmological dark matter simulations of

We investigate how strong gravitational lensing in the concordanceCDM cosmology is affected by the stellar mass in galaxies. We extend our previous studies, based on ray trac- ing through the
Core Mass Estimates in Strong Lensing Galaxy Clusters Using a Single-halo Lens Model
The core mass of galaxy clusters is an important probe of structure formation. Here we evaluate the use of a single-halo model (SHM) as an efficient method to estimate the strong lensing cluster core
Strong lensing statistics and the power spectrum normalisation
We use semi-analytic modelling of the galaxy-cluster population and its strong lensing efficiency to explore how the expected abundance of large gravitational arcs on the sky depends on σ 8 . Our
Statistics of giant arcs in galaxy clusters
We study the expected properties and statistics of giant arcs produced by galaxy clusters in a ΛCDM (cold dark matter) universe and investigate how the characteristics of CDM clusters determine the
Mass Distributions of HST Galaxy Clusters from Gravitational Arcs
Although N-body simulations of cosmic structure formation suggest that dark matter halos have density profiles shallower than isothermal at small radii and steeper at large radii, whether observed
Constraining the abundance of dark matter in the central region of the galaxy cluster MACS J1206.2−0847 with a free-form strong lensing analysis
We performed a free-form strong lensing analysis of the galaxy cluster MACS J1206.2−0847 in order to estimate and constrain its inner dark matter distribution. The free-form method estimates the

Clustering of galaxies in a hierarchical universe - I. Methods and results at z=0
We introduce a new technique for following the formation and evolution of galaxies in cosmological N-body simulations. Dissipationless simulations are used to track the formation and merging of dark

High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” profile. Regardless
The Incidence of Strong-Lensing Clusters in the Red-Sequence Cluster Survey
The incidence of giant arcs due to strong-lensing clusters of galaxies is known to be discrepant with current theoretical expectations. This result derives from a comparison of several cluster
Probing the Core Structure of Dark Halos with Tangential and Radial Arc Statistics

Cluster cross‐sections for strong lensing: analytic and numerical lens models
The statistics of gravitationally lensed arcs was recognized earlier as a potentially powerful cosmological probe. However, while fully numerical models find orders of magnitude difference between
