. Merging cluster DLSCL J0916.2+2951 and its three matter components. Overlaid on the Hubble Space Telescope (HST) color image of the galaxies is the total mass distribution (blue) based on WL analysis of the HST images and the cluster gas distribution (red) based on Chandra X-ray observations. The bulk of the collisional gas is located between the two collisionless galaxy and mass concentrations, indicative of a dissociative merger.
