Tracing Structure: Shape and Centroid Deviations in 39 Strong Lensing Clusters as a Test of Cluster Formation Predictions

Raven Gassis, Matthew B. Bayliss, Keren Sharon +10

Strong lensing galaxy clusters provide a unique and powerful way to test simulation-derived structure predictions that follow from Cold Dark Matter (CDM) cosmology. Specific…

The Chandra Strong Lens Sample: Measuring the Dynamical States and Relaxation Fraction of a Sample of 28 Strong Lensing Selected Galaxy Clusters

Raven Gassis, Matthew B. Bayliss, Michael McDonald +10

We present the results of our dynamical state proxy measurements performed on 28 strong lensing galaxy clusters from the Sloan Giant Arcs Survey (SGAS). Using Chandra ACIS-I/S X-ra…

Understanding Shape and Centroid Deviations in 39 Strong Lensing Galaxy Clusters in Various Dynamical States

Raven Gassis, Matthew B. Bayliss, Keren Sharon +8

Through observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Cold Dark Matter (CDM) cosmology. The sh…

The importance of secondary halos for strong lensing in massive galaxy clusters across redshift

Nan Li, Michael D. Gladders, Katrin Heitmann +6

Cosmological cluster-scale strong gravitational lensing probes the mass distribution of the dense cores of massive dark matter halos and the structures along the line of sight from…
