Cluster deprojection with joint lensing, X-ray, and Sunyaev-Zeldovich data
Katrin Reblinsky, Matthias Bartelmann
We propose a new cluster deprojection algorithm for recovering cluster structure along the line of sight (los) based on the Richardson-Lucy (RL) algorithm, which recovers a nonnega…
High-redshift quasars lensed by spiral galaxies
Matthias Bartelmann
Given its extraordinary spatial resolution and sensitivity, the projected Next Generation Space Telescope (NGST) is likely to detect a large number of high-redshift QSOs lensed by…
SPH simulations of magnetic fields in galaxy clusters (proceedings)
Klaus Dolag, Matthias Bartelmann, Harald Lesch
We perform cosmological, hydrodynamic simulations of magnetic fields in galaxy clusters. The computational code combines the special-purpose hardware Grape for calculating gravitat…

Projection effects in mass-selected galaxy-cluster samples
Katrin Reblinsky, Matthias Bartelmann
Selection of galaxy clusters by mass is now possible due to weak gravitational lensing effects. It is an important question then whether this type of selection reduces the projecti…
Power spectrum from weak-shear data
Matthias Bartelmann, Peter Schneider
We demonstrate that the aperture mass as a measure for cosmic shear closely approximates (to better than ~5%) the scaled and shifted power spectrum of the projected mass density. T…
