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…

Line of Sight Bias in Dark Matter Inferences from Galaxy Cluster Mergers
David Wittman, Scott Adler, Rodrigo Stancioli
In collisions of galaxy clusters, the lack of displacement between dark matter and galaxies suggests that the dark matter scattering depth is small. This yields an upper limit on t…

Magnetic quantum criticality: The role of the Fermi surface geometry
S. Adler, D. R. Fus, M. O. Malcolms +5
We investigate magnetic quantum phase-transitions in bulk correlated metals. To this end, we focus on the Hubbard model on different cubic lattices as a function of temperature and…
