Galaxy Clusters and Dark Matter Properties
J. S. Arabadjis, M. W. Bautz
Laboratory experiments, large-scale computer simulations and observational cosmology have begun to make progress in the campaign to identify the particle responsible for gravitatio…
Mass Profiles of Galaxy Cluster Cores: Implications for Structure Formation and Self-Interacting Dark Matter
J. S. Arabadjis, M. W. Bautz
We present a spectroscopic deprojection analysis of a sample of ten relaxed galaxy clusters. We use an empirical F-test derived from a set of Markov Chain Monte Carlo simulations t…
Constraining Multiphase Gas in Cooling Flows
J. S. Arabadjis, M. W. Bautz
We present a spectral analysis of the central X-ray emission for a sample of galaxy clusters observed with Chandra. We constrain the quantity of a second cospatial temperature comp…
The Dark Matter Distribution in Galaxy Cluster Cores
M. W. Bautz, J. S. Arabadjis
Galaxy cluster mass distributions offer an important test of the cold dark matter picture of structure formation, and may even contain clues about the nature of dark matter. X-ray…
Chandra Observations and the Mass Distribution of EMSS1358+6245: Toward Constraints on Properties of Dark Matter
M. W. Bautz, J. S. Arabadjis, G. P. Garmire
Chandra observations of lensing galaxy clusters have now provided accurate dark matter profiles for several objects in which the intracluster medium is likely to be in hydrostatic…
The Dynamical Evolution of Dense Rotating Systems: Paper II. Mergers and Stellar Evolution
John S. Arabadjis, Douglas O. Richstone
We report the results of simulations of dense rotating stellar systems whose members suffer collisions and undergo stellar evolution processes. The initial configuration for each e…
