X-ray measurements of the aspherical mass distribution in the clusterof galaxies A 2256.
Abstract
The authors describe a technique for deriving the underlying mass distribution from X-ray surface brightness maps of rich clusters of galaxies with a smooth X-ray morphology and approximate bilateral symmetry. They apply this technique to A 2256 and find significant departures from spherical symmetry.
