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…
Very Isolated Early-Type Galaxies
J. T. Stocke, B. A. Keeney, A. D. Lewis +2
We use the Karachentseva (1973) ``Catalogue of Very Isolated Galaxies'' to investigate a candidate list of >100 very isolated early-type galaxies. Broad-band imaging and low resolu…
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…
Chandra Observations of Abell 2029: The Dark Matter Profile Down to <0.01 R_vir in an Unusually Relaxed Cluster
Aaron D. Lewis, David A. Buote, John T. Stocke
We have used a high resolution Chandra observation to examine the core mass distribution of the unusually regular cD cluster Abell 2029. This system is especially well-suited for a…
Chandra Observations of Abell 2029: No Cooling Flow and a Steep Abundance Gradient
Aaron D. Lewis, John T. Stocke, David A. Buote
We have obtained high spatial resolution temperature and abundance profiles for the galaxy cluster Abell 2029 with the Chandra ACIS-S instrument. Our observations reveal that the s…
