On the properties of ten strong-lensing systems found in the Sloan Digital Sky Survey

In this thesis, we describe a study of ten strong gravitational lenses. These lensing systems were discovered in the Sloan Digital Sky Survey by the Sloan Bright Arcs Survey. We took data on these systems with much better resolution and reduced and calibrated the data. We then studied the properties of the galaxy clusters of which the lenses were a part and the properties of the strong lenses themselves. We present results for the richness (N200), mass (M200) and velocity dispersion of the clusters. We also present results for the Einstein radius, mass and velocity dispersion of the strong lenses. Finally, we find a relation between the Einstein radii and the cluster masses and we compare this relation to the findings of other groups.
