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. 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…

SLICE: SPT-CL J0546-5345 -- A prominent strong-lensing cluster at

Joseph F. V. Allingham, Adi Zitrin, Miriam Golubchik +15

Massive galaxy clusters act as prominent strong-lenses. Due to a combination of observational biases, cluster evolution and lensing efficiency, most of the known cluster lenses lie…

Connecting Lyman- and ionizing photon escape in the Sunburst Arc

M. Riley Owens, Keunho J. Kim, Matthew B. Bayliss +17

We investigate the Lyman- (Ly) and Lyman continuum (LyC) properties of the Sunburst Arc, a gravitationally lensed galaxy with a multiply-imaged, compact region leaki…
