Evolution of linear perturbations in Lemaître-Tolman-Bondi void models
Sven Meyer, Matthias Redlich, Matthias Bartelmann
We study the evolution of linear perturbations in a Lemaître-Tolman-Bondi (LTB) void model with realistic cosmological initial conditions. Linear perturbation theory in LTB models…
The strongest gravitational lenses: IV. The order statistics of the largest Einstein radii with cluster mergers
Matthias Redlich, Jean-Claude Waizmann, Matthias Bartelmann
Based on techniques developed in the previous papers of this series, we investigate the impact of galaxy-cluster mergers on the order statistics of the largest Einstein radii. We s…
Probing spatial homogeneity with LTB models: a detailed discussion
Matthias Redlich, Krzysztof Bolejko, Sven Meyer +2
Do current observational data confirm the assumptions of the cosmological principle, or is there statistical evidence for deviations from spatial homogeneity on large scales? To ad…
The strongest gravitational lenses: III. The order statistics of the largest Einstein radii
Jean-Claude Waizmann, Matthias Redlich, Massimo Meneghetti +1
The Einstein radius (ER) of a gravitational lens encodes information about decisive quantities such as halo mass, concentration, triaxiality, and orientation with respect to the ob…
