We present new weak lensing observations of 1E0657-558 (z = 0.296), a unique cluster merger, that enable a direct detection of dark matter, independent of assumptions regarding the nature of the gravitational force law. Due to the collision of two clusters, the dissipationless stellar component and the fluid-like X-ray emitting plasma are spatially segregated. By using both wide-field ground based images and HST/ACS images of the cluster cores, we create gravitational lensing maps which show… Expand

On the proof of dark matter, the law of gravity, and the mass of neutrinos
We develop a new method to predict the density associated with weak-lensing maps of (un)relaxed clusters in a range of theories interpolating between general relativity (GR) and modified NewtonianExpand
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
Revealing the Properties of Dark Matter in the Merging Cluster MACS J0025.4–1222
We constrain the physical nature of dark matter using the newly identified massive merging galaxy cluster MACS J0025.4−1222. As was previously shown by the example of the Bullet Cluster (1E065756),Expand
Light/mass offsets in the lensing cluster Abell 3827: evidence for collisional dark matter?
If dark matter has a non-zero self-interaction cross-section, then dark matter haloes of individual galaxies in cluster cores should experience a drag force from the ambient dark matter of theExpand
ON THE SEPARATION BETWEEN BARYONIC AND DARK MATTER: EVIDENCE FOR PHANTOM DARK MATTER?
The recent years have seen combined measurements of X-ray and (weak) lensing contours for colliding galaxy clusters such as, for instance, the famous 'Bullet' cluster. These observations haveExpand
The dark matter of gravitational lensing
We review progress in understanding dark matter by astrophysics, and particularly via the effect of gravitational lensing. Evidences from many different directions now all imply that five sixths ofExpand
Mapping Dark Matter and Dark Energy
We measure the ellipticity of isolated clusters of galaxies in the Sloan Digital Sky Survey (SDSS) using gravitational lensing. We stack the clusters, rotating so that the major axes of the ellipsesExpand
Detection of universality of dark matter profile from Subaru weak lensing measurements of 50 massive clusters
We develop a novel method of measuring the lensing distortion profiles of clusters with stacking the scaled amplitudes of background galaxy ellipticities as a function of the scaled centric radiusExpand
Dark matter maps reveal cosmic scaffolding
TLDR
These results are consistent with predictions of gravitationally induced structure formation, in which the initial, smooth distribution of dark matter collapses into filaments then into clusters, forming a gravitational scaffold into which gas can accumulate, and stars can be built. Expand
Offset between dark matter and ordinary matter: evidence from a sample of 38 lensing clusters of galaxies
We compile a sample of 38 galaxy clusters which have both X-ray and strong lensing observations, and study for each cluster the projected offset between the dominant component of baryonic matterExpand

Weak-lensing mass reconstruction of the interacting cluster 1E 0657-558: Direct evidence for the existence of dark matter
We present a weak-lensing mass reconstruction of the interacting cluster 1E 0657-558, in which we detect both the main cluster and a subcluster. The subcluster is identified as a smaller cluster thatExpand
