We use gravitational lens models and X-ray spectral analysis of 10 X-ray-luminous galaxy clusters at z sime 0.2 to study the impact of cluster substructure on attempts to normalize the matter power spectrum. We estimate that unrelaxed clusters are 30... Read More about Measuring σ₈ with Cluster Lensing: Biases from Unrelaxed Clusters..
