A Consistent Implementation of Cluster Strong Lensing in Cosmological Simulation Light Cones
Cian Roche, Mark Vogelsberger, Michael McDonald +9
Galaxy cluster strong gravitational lensing plays a central role in precision cosmology, yet robust theoretical predictions have lagged behind an abundance of high-quality strong l…
Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters
Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93
The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…
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. Specif…
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…
Multiprobe Cosmology from the Abundance of SPT Clusters and DES Galaxy Clustering and Weak Lensing
S. Bocquet, S. Grandis, E. Krause +216
Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the Universe in complementary ways. We present cosmological constraints…
