Merging clusters of galaxies are unique in their power to directly probe and place limits on the self-interaction cross-section of dark matter. Detailed observations of several merging clusters have shown the intracluster gas to be displaced from the centroids of dark matter and galaxy density by ram pressure, while the latter components are spatially coincident, consistent with collisionless dark matter. This has been used to place upper limits on the dark matter particle self-interaction… Expand

A STUDY OF THE DARK CORE IN A520 WITH THE HUBBLE SPACE TELESCOPE: THE MYSTERY DEEPENS*
We present a Hubble Space Telescope/Wide Field Planetary Camera 2 weak-lensing study of A520, where a previous analysis of ground-based data suggested the presence of a dark mass concentration. WeExpand
Sparse reconstruction of the merging A520 cluster system
Merging galaxy clusters present a unique opportunity to study the properties of dark matter in an astrophysical context. These are rare and extreme cosmic events in which the bulk of the baryonicExpand
On the cross-section of dark matter using substructure infall into galaxy clusters
We develop a statistical method to measure the interaction cross-section of dark matter, exploiting the continuous minor merger events in which small substructures fall into galaxy clusters. We findExpand
Hubble Space Telescope/Advanced Camera for Surveys Confirmation of the Dark Substructure in A520
We present the results from a weak gravitational lensing study of the merging cluster A520 based on the analysis of Hubble Space Telescope/Advanced Camera for Surveys (ACS) data. The excellent dataExpand
The distribution of dark and luminous matter in the unique galaxy cluster merger Abell 2146.
Abell 2146 (z = 0.232) consists of two galaxy clusters undergoing a major merger. The system was discovered in previous work, where two large shock fronts were detected using the Chandra X-rayExpand
In the wake of dark giants: new signatures of dark matter self-interactions in equal-mass mergers of galaxy clusters
Author(s): Kim, SY; Peter, AHG; Wittman, D | Abstract: © 2017 The Authors. Merging galaxy clusters have been touted as one of the best probes for constraining selfinteracting darkmatter, butExpand
The merging galaxy cluster A520 --- a broken-up cool core, a dark subcluster, and an X-ray channel
We present results from a deep Chandra X-ray observation of a merging galaxy cluster A520. A high-resolution gas temperature map, after the subtraction of the cluster-scale emission, reveals a longExpand
The behaviour of dark matter associated with four bright cluster galaxies in the 10 kpc core of Abell 3827
Galaxy cluster Abell 3827 hosts the stellar remnants of four almost equally bright elliptical galaxies within a core of radius 10 kpc. Such corrugation of the stellar distribution is very rare, andExpand
Dark matter dynamics in Abell 3827: New data consistent with standard cold dark matter
We present integral field spectroscopy of galaxy cluster Abell 3827, using Atacama Large Millimetre Array (ALMA) and Very Large Telescope/Multi-Unit Spectroscopic Explorer. It reveals an unusualExpand
Galaxy cluster studies with weak lensing magnification & shear
Clusters of galaxies offer a unique window for studying the Universe on the largest scales. As the most massive gravitationally bound systems to have formed, they serve as probes of the large-scaleExpand
