The Dark Matter Radial Profile in the Core of the Relaxed Cluster A2589
David A. Buote, Aaron D. Lewis
We present an analysis of a Chandra--ACIS observation of the galaxy cluster A2589 to constrain the radial distribution of the total gravitating matter and the dark matter in the co…

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…

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…
