Aims. We investigate how ellipticity, asymmetries and substructures separately affect the ability of galaxy clusters to produce strong lensing events, i.e. gravitational arcs, and how they influence the a rc morphologies and fluxes. This is important for those studi es aiming, for example, at constraining cosmological parameters from statistical lensing, or at determining the inner structure of galaxy clu sters through gravitational arcs. Methods. We do so by creating two-dimensional smoothed… 
Cosmography with cluster strong lenses: the influence of substructure and line-of-sight haloes
We explore the use of strong lensing by galaxy clusters to constrain the dark energy equation of state and its possible time variation. The cores of massive clusters often contain several multiply
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
Strong lensing in the MARENOSTRUM UNIVERSE - I. Biases in the cluster lens population
Context. Strong lensing is one of the most direct probes of mass distribution in the inner regions of galaxy clusters. It can be used to constrain the density profiles and to measure the mass of the
Numerical investigation of lens models with substructures using the perturbative method
We present a statistical study of the effects induced by substructures on the deflection potential of dark matter haloes in the strong lensing regime. This investigation is based on the pertubative
Strong lensing in the inner halo of galaxy clusters
We present an axially symmetric formula to calculate the probability of finding gravitational arcs in galaxy clusters, being induced by their massive dark matter haloes, as a function of clusters
Strong lensing in Abell 1703: constraints on the slope of the inner dark matter distribution
Properties of dark matter haloes can be probed observationally and numerically, and comparing both approaches provides ways to constrain cosmological models. When it comes to the inner part of galaxy
Comparison of an X-ray-selected sample of massive lensing clusters with the MareNostrum Universe ΛCDM simulation
Context. A long-standing problem of strong-lensing by galaxy clusters is the observed high rate of giant gravitational arcs that are not predicted in the framework of the “standard” cosmological
Substructures in hydrodynamical cluster simulations
The abundance and structure of dark matter subhaloes have been analysed extensively in recent studies of dark-matter-only simulations, but comparatively little is known about the impact of baryonic
Strong lensing in the MARENOSTRUM UNIVERSE II. Scaling relations and optical depths
The strong lensing events that are observed in compact clusters of galaxies can, both statistically and individually, return important clues about the structural properties of the most massive
Towards noiseless gravitational lensing simulations
The microphysical properties of the DM particle can, in principle, be constrained by the properties and abundance of substructures in DM halos, as measured through strong gravitational lensing.


The impact of cluster mergers on arc statistics
We study the impact of merger events on the strong lensing properties of galaxy clusters. Previous lensing simulations were not able to resolve dynamical time scales of cluster lenses, which arise on
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
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
Systematic Effects on Tangential and Radial Arc Statistics: The Finite Source Size and Ellipticities of the Lens and Source
It has been recognized that the arc statistics of gravitational lensing are a useful probe of the density profile of clusters of galaxies. We examine several systematic effects that are important in
Effects of cluster galaxies on arc statistics
We present the results of a set of numerical simulations evaluating the effect of cluster galaxies on arc statistics. We perform a first set of gravitational lensing simulations using three
Noise in strong lensing cosmography
Giant arcs in strong lensing galaxy clusters can provide a purely geometric determination of cosmological parameters, such as the dark energy density and equation of state. We investigate sources of
A fast method for computing strong-lensing cross sections: application to merging clusters
Astronomy & Astrophysics, submitted Abstract. Strong gravitational lensing by irregular mass distributi ons, such as galaxy clusters, is generally not well quantifie d by cross sections of analytic
Arc Statistics in Clusters: Galaxy Contribution
The frequency with which background galaxies appear as long arcs as a result of gravitational lensing by foreground clusters of galaxies has recently been found by Bartelmann et al. to be a very
Giant cluster arcs as a constraint on the scattering cross-section of dark matter
We carry out ray tracing through five high resolution simulat ions of a galaxy cluster to study how its ability to produce giant gravitationally lens ed arcs is influenced by the collision
The impact of gas physics on strong cluster lensing
Previous studies of strong gravitational lensing by galaxy clusters have neglected the potential impact of the intracluster gas. Here, we compare simulations of strong cluster lensing including gas
