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…
Studying Dark Energy with Galaxy Cluster Surveys
Joseph J. Mohr, Brian OShea, August E. Evrard +2
Galaxy cluster surveys provide a powerful means of studying the density and nature of the dark energy. The redshift distribution of detected clusters in a deep, large solid angle S…
A Cold Front in a Preheated Galaxy Cluster
John J. Bialek, August E. Evrard, Joseph J. Mohr
We present a simulated cluster of galaxies, modeled with a pre-heated intracluster medium, that exhibits X-ray features similar to the `cold fronts' seen in Chandra observations. M…
Effects of Preheating on X-ray Scaling Relations in Galaxy Clusters
John J. Bialek, August E. Evrard, Joseph J. Mohr
The failure of purely gravitational models of X-ray cluster formation to reproduce basic observed properties of the local cluster population suggests the need for one or more addit…
