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…
A Very Rich Bimodal Galaxy Cluster Merger: RXC J0032.1+1808
David Wittman, Rodrigo Stancioli, Faik Bouhrik +3
The galaxy cluster RXC J0032.1+1808 has been well-studied with optical imaging and gravitational lensing mass maps, both of which reveal an elongated morphology in the north-south…
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…
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…
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…
Intermediate phase and pseudo phase transition in an artificial spin ice model
R. A. Stancioli, L. A. S. Mól
In this paper we conduct Monte Carlo simulations to investigate the thermodynamic properties of a geometry of artificial spin ice recently proposed in the literature that had been…
On the use of the energy probability distribution zeros in the study of phase transitions
L A S Mól, R G M Rodrigues, R A Stancioli +2
This contribution is devoted to cover some technical aspects related to the use of the recently proposed energy probability distribution zeros in the study of phase transitions. Th…
