We have undertaken a spectroscopic survey of gravitational arcs in a carefully chosen sample of six clusters, each containing a dominant brightest cluster galaxy. We use these systems to study the relative distributions of dark and baryonic material in the central regions. Three clusters present both radial and tangential arcs and provide particularly strong constraints on the mass profiles, whereas the other three display only tangential arcs and act as a control set. Following Sand, Treu…

Constraining the cross-section of dark matter with giant radial arcs in galaxy clusters

We compare the statistics and morphology of giant arcs in galaxy clusters using N-body simulations within the standard cold dark matter model and simulations where dark matter has a non-negligible

Mass Distributions of Hubble Space Telescope Galaxy Clusters from Gravitational Arcs

We present a detailed analysis of the baryonic and dark matter distribution in the lensing cluster Abell 611 (z = 0.288), with the goal of determining the dark matter profile over an unprecedented

Mass Distribution in Galaxy Cluster Cores

Many processes within galaxy clusters, such as those believed to govern the onset of thermally unstable cooling and active galactic nucleus feedback, are dependent upon local dynamical timescales.
