The impact of gas physics on strong cluster lensing
Ewald Puchwein, Matthias Bartelmann, Klaus Dolag +1
Previous studies of strong gravitational lensing by galaxy clusters neglected the potential impact of the intracluster gas. Here, we compare simulations of strong cluster lensing i…
Arc statistics with realistic cluster models
Massimo Meneghetti, Matthias Bartelmann, Lauro Moscardini +3
Arc statistics is known to be a powerful cosmological tool. Numerical lensing simulations show that orders of magnitude differences in the number of {\em giant} arcs on the whole s…
Numerical Methods in Gravitational Lensing
Matthias Bartelmann
Most problems in gravitational lensing require numerical solutions. The most frequent types of problems are (1) finding multiple images of a single source and classifying the image…
Strong and weak lensing by galaxy clusters
Matthias Bartelmann
I present an overview of strong and weak gravitational lensing by galaxy clusters. After briefly introducing the principles of gravitational lensing, I discuss the main lessons lea…
Clustering properties and gravitational lensing of forming spheroidal galaxies
F. Perrotta, M. Magliocchetti, C. Baccigalupi +5
We show that the predictions of the recent physical model by Granato et al. (2001) are fully consistent with the available estimates of the clustering properties of galaxies at (su…
The Evolution of Magnetic Fields in Galaxy Clusters
Matthias Bartelmann, Klaus Dolag, Harald Lesch
Cosmological simulations of magnetic fields in galaxy clusters show that remarkable agreement between simulations and observations of Faraday rotation and radio haloes can be achie…
