A New Galaxy Cluster Merger Capable of Probing Dark Matter: Abell 56
David Wittman, Rodrigo Stancioli, Kyle Finner +3
We report the discovery of a binary galaxy cluster merger via a search of the redMaPPer optical cluster catalog, with a projected separation of 535 kpc between the BCGs. Archival X…
A New Dissociative Galaxy Cluster Merger: RM J150822.0+575515.2
Rodrigo Stancioli, David Wittman, Kyle Finner +1
Galaxy cluster mergers that exhibit clear dissociation between their dark matter, intracluster gas, and stellar components are great laboratories for probing dark matter properties…
Testing Velocity-Field Lensing on IllustrisTNG Galaxies
Jean Donet, David Wittman
Weak gravitational lensing shear could be measured far more precisely if information about unlensed attributes of source galaxies were available. Disk galaxy velocity fields supply…
Exemplary Merging Clusters: Weak-lensing and X-ray Analysis of the Double Radio Relic Merging Galaxy Clusters MACS 1752.0+4440 and ZWCL 1856.8+6616
Kyle Finner, Kim HyeongHan, M. James Jee +8
The investigation of merging galaxy clusters that exhibit radio relics is strengthening our understanding of the formation and evolution of galaxy clusters, the nature of dark matt…
Chandra Observations of the Spectacular A3411-12 Merger Event
Felipe Andrade-Santos, Reinout J. van Weeren, Gabriella Di Gennaro +17
We present deep Chandra observations of A3411-12, a remarkable merging cluster that hosts the most compelling evidence for electron re-acceleration at cluster shocks to date. Using…
Precision Weak Gravitational Lensing Using Velocity Fields: Fisher Matrix Analysis
David Wittman, Matthew Self
Weak gravitational lensing measurements based on photometry are limited by shape noise, the variance in the unknown unlensed orientations of the source galaxies. If the source is a…
