2. Frontier Fields Lensing Models
... HST . ... Lensing Models . ... In order to interpret many of the properties of background lensed galaxies, reliable models of the lensing maps for each cluster are required. Preliminary models for each of the six Frontier Fields clusters have been provided by five independent groups prior to the HST Frontier Fields observing campaign in order to facilitate rapid analysis of the FF data by all members of the community. ... The various groups model the cluster mass distribution in different ways. ...

3. APOD: 2007 May 16 - Dark Matter Ring Modeled around Galaxy Cluster CL0024 17
... Dark Matter Ring Modeled around Galaxy Cluster CL0024+17 . ... It is the relatively weak distortions of the many distant faint blue galaxies all over the image, however, that indicates the existence of the dark matter ring. ... A hypothesis for the formation of the huge dark matter ring holds that it is a transient feature formed when galaxy cluster CL0024+17 collided with another cluster of galaxies about one billion years ago, leaving a ring similar to when a rock is thrown in a pond. ...
