We investigated the X-ray and mass distribution in the merging galaxy cluster 1E 0657−56. We also studied head-on collisions of two virialized clusters with an NFW density profile in the ΛCDM universe using an N-body plus hydrodynamical code. A clear off-set of an X-ray peak from a mass peak, which is like what is reported in Clowe, Gonzalez, and Markevitch (2004), was first reproduced in N-body plus hydrodynamical simulations. We estimated the ram pressure-stripping conditions of the…

Constraints on the Self-Interaction Cross Section of Dark Matter from Numerical Simulations of the Merging Galaxy Cluster 1E 0657?56
We compare recent results from X-ray, strong lensing, weak lensing, and optical observations with numerical simulations of the merging galaxy cluster 1E 0657–56. X-ray observations reveal a
The relationship between substructure in 2D X-ray surface brightness images and weak-lensing mass maps of galaxy clusters: a simulation study
Recent X-ray and weak-lensing observations of galaxy clusters have revealed that the hot gas does not always directly trace the dark matter within these systems. Such configurations are extremely
The Cluster-Merger Shock in 1E 0657-56
The merging galaxy cluster 1E 0657-56, known as the "bullet cluster," is one of the hottest clusters known. The X-ray emitting plasma exhibits bow-shock-like temperature and density jumps. The
Simulations of the merging galaxy cluster Abell 3376
Observed galaxy clusters often exhibit X-ray morphologies suggestive of recent interaction with an infalling subcluster. Abell 3376 is a nearby (z=0.046) massive galaxy cluster whose bullet-shaped
The speed of the ‘bullet’ in the merging galaxy cluster 1E0657−56
Deep Chandra exposures of the hot galaxy cluster 1E0657-56 have revealed a highly dynamical state of the system due to an ongoing merger with a massive subcluster. The system is observed shortly
Subaru Weak Lensing Study of Seven Merging Clusters: Distributions of Mass and Baryons
We present and compare projected distributions of mass, galaxies, and the intracluster medium (ICM) for a sample of merging clusters of galaxies based on the joint weak-lensing, optical photometric,
Mass Estimation of Merging Galaxy Clusters
We investigate the impact of mergers on the mass estimation of galaxy clusters using N -body + hydrodynamical simulation data. We estimate the virial mass from these data and compare it with the real

Simulating the shocks in the dissociative galaxy cluster Abell 1758N
Major mergers between massive clusters have a profound effect in the intracluster gas, which may be used as a probe of the dynamics of structure formation at the high end of the mass function. An

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 that
