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 Evolution of Cluster Substructure with Redshift
Tesla E. Jeltema, Claude R. Canizares, Mark W. Bautz +1
Using Chandra archival data, we quantify the evolution of cluster morphology with redshift. To quantify cluster morphology, we use the power ratio method developed by Buote and Tsa…
Circulation Flows: Cooling Flows with Bubble Return
William G. Mathews, Fabrizio Brighenti, David A. Buote +1
The failure of the XMM-Newton and Chandra X-ray telescopes to detect cooling gas in elliptical galaxies and clusters of galaxies has led many to adopt the position that the gas is…
The Evolution of Cluster Substructure
Tesla E. Jeltema, Claude R. Canizares, Mark W. Bautz +1
Using Chandra archival data, we have begun a study to quantify the evolution of cluster morphology with redshift. To quantify cluster morphology, we use the power ratio method deve…
XMM-Newton and Chandra Observations of the Galaxy Group NGC 5044. II. Metal Abundances and Supernova Fraction
David A. Buote, Aaron D. Lewis, Fabrizio Brighenti +1
Using new XMM and Chandra observations we present an analysis of the metal abundances of the hot gas within a radius of 100 kpc of the bright nearby galaxy group NGC 5044. Motivate…
