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…
Consistent use of Type Ia supernovae highly magnified by galaxy clusters to constrain the cosmological parameters
Adi Zitrin, Matthias Redlich, Tom Broadhurst
We discuss how Type Ia supernovae (SNe) strongly magnified by foreground galaxy clusters should be self-consistently treated when used in samples fitted for the cosmological parame…
The strongest gravitational lenses: II. Is the large Einstein radius of MACS J0717.5+3745 in conflict with LCDM?
Jean-Claude Waizmann, Matthias Redlich, Matthias Bartelmann
Can the standard cosmological model be questioned on the basis of a single observed extreme galaxy cluster? Usually, the word extreme refers directly to cluster mass, which is not…
The strongest gravitational lenses: I. The statistical impact of cluster mergers
Matthias Redlich, Matthias Bartelmann, Jean-Claude Waizmann +1
For more than a decade now, it has been controversial whether or not the high rate of giant gravitational arcs and the largest observed Einstein radii are consistent with the stand…
