Evolution of the Intracluster Medium Between 0.2 < z < 1.3 in a Chandra Sample of 70 Galaxy Clusters
T. B. O'Hara, J. J. Mohr, A. J. R. Sanderson
We study the evolution of the ICM with a sample of 70 galaxy clusters spanning 0.18 < z < 1.24. We find that X-ray luminosity and ICM mass at a fixed temperature evolve with redshi…

Effects of Mergers and Core Structure on the Bulk Properties of Nearby Galaxy Clusters
Timothy B. O'Hara, Joseph J. Mohr, John J. Bialek +1
We use morphological measurements and the scatter of clusters about observed and simulated scaling relations to examine the impact of merging and core-related phenomena on the stru…

A Chandra Study of the Effects of a Major Merger on the Structure of Abell 2319
Timothy B. O'Hara, Joseph J. Mohr, Martin A Guerrero
We present an analysis of a Chandra observation of the massive, nearby galaxy cluster Abell 2319. A sharp surface brightness discontinuity--suggested by previous, lower angular res…
