Weighting the Clusters of Galaxies with Weak Gravitational Lensing: The problem of the mass-sheet degeneracy
M. Bradac, M. Lombardi, P. Schneider
Weak gravitational lensing is considered to be one of the most powerful tools to study the mass and the mass distribution of galaxy clusters. However, weak lensing mass reconstruct…

Using VLBI Data to Investigate the Galaxy Structure in the Gravitationally Lensed System B1422+231
M. Bradac, P. Schneider, M. Steinmetz +3
Gravitationally lensed systems with multiply imaged quasars are an excellent tool for studying the properties of distant galaxies. In particular, they provide the most accurate mas…
