Toward Detecting the Moving Lens Effect with Optical Spectroscopy
David Wittman, Rodrigo Stancioli, Christopher Hopp
Relativity predicts that sky-plane motion of a gravitational lens changes the wavelengths of lensed photons. This moving lens effect is orders of magnitude smaller than cosmologica…
X-SORTER (X-ray Survey Of meRging clusTErs in Redmapper): X-ray and Spectroscopic Characterization of 12 Optically Selected Galaxy Cluster Merger Candidates
Christopher Hopp, David Wittman, Rodrigo Stancioli +3
Merging galaxy clusters offer a unique probe of dark matter (DM) interactions through the spatial offsets between galaxies, the intracluster medium, and the DM halo. Systems that a…
Discovery and Multi-Wavelength Analysis of a New Dissociative Galaxy Merger: The Champagne Cluster
Faik Bouhrik, Rodrigo Stancioli, David Wittman
We report the discovery of a new binary galaxy cluster merger, the Champagne Cluster (RM J130558.9+263048.4), using a detection method that identifies dynamically active clusters i…
Weak-Lensing Characterization of the Dark Matter in 29 Merging Clusters that Exhibit Radio Relics
Kyle Finner, M. James Jee, Hyejeon Cho +5
We present a multiwavelength analysis of 29 merging galaxy clusters that exhibit radio relics. For each merging system, we perform a weak-lensing analysis on Subaru optical imaging…
Abell 746: A highly disturbed cluster undergoing multiple mergers
K. Rajpurohit, L. Lovisari, A. Botteon +21
We present deep XMM-Newton, Karl Jansky Very Large Array, and upgraded Giant Metrewave Radio Telescope observations of Abell 746, a cluster that hosts a plethora of diffuse emissio…
Merging Cluster Collaboration: Optical and Spectroscopic Survey of a Radio-Selected Sample of Twenty Nine Merging Galaxy Clusters
Nathan Golovich, William A. Dawson, David M. Wittman +11
Multi-band photometric and multi-object spectroscopic surveys of merging galaxy clusters allow for the characterization of the distributions of constituent dark matter and galaxy p…
