X-Ray Constraints on Dark Matter in Galaxy Clusters and Elliptical Galaxies: A View from Chandra and XMM
David A. Buote
I review constraints on the radial density profiles and ellipticities of the dark matter obtained from recent X-ray observations with Chandra and XMM of elliptical galaxies and gal…

The Shapes and Sizes of Elliptical Galaxy Halos from X-Ray Observations
David A. Buote, Claude R. Canizares
We review the theory of how the shapes of the X-ray isophotes probe both the shape and radial distribution of gravitating matter in elliptical galaxies in a way that is more robust…

X-ray Measurements of the Shapes of Clusters and Galaxies
Claude R. Canizares, David A. Buote
We summarize a series of papers reporting studies of the ellipticities of X-ray images of five Abell clusters and two early type galaxies to learn about the shape of the gravitatio…
