Reionisation scenarios and the temperature of the IGM
Eric R. Tittley, Avery Meiksin
We examine the temperature structure of the IGM due to the passage of individual ionisation fronts using a radiative transfer (RT) code coupled to a particle-mesh (PM) N-body code.…
Cluster mergers, core oscillations, and cold fronts
Eric R. Tittley, Mark Henriksen
We use numerical simulations with hydrodynamics to demonstrate that a class of cold fronts in galaxy clusters can be attributed to oscillations of the dark matter distribution. The…
XMM-Newton Observation of the Merging Galaxy Cluster A1644
Thomas H. Reiprich, Craig L. Sarazin, Joshua C. Kempner +1
An XMM-Newton imaging spectroscopy analysis of the galaxy cluster A1644 is presented. A1644 is a complex merging system consisting of a main and a sub cluster. A trail of cool, met…
A Soft X-ray Component in the Abell 754 Cluster
Mark J. Henriksen, Daniel S. Hudson, Eric Tittley
We have analyzed the Chandra, BeppoSax, and ROSAT observations of Abell 754 and report evidence of a soft, diffuse X-ray component. The emission is peaked in the cluster center and…
Chandra Observations of the A3266 Galaxy Cluster Merger
Mark J. Henriksen, Eric R. Tittley
Analysis of a 30,000 s X-ray observation of the Abell 3266 galaxy cluster with the ACIS on board the Chandra Observatory has produced several new insights into the cluster merger.…
Resolving the jeans mass in hydrodynamic simulations of hierarchical clustering
Eric R. Tittley, H. M. P. Couchman
We examine the necessity of resolving the Jeans mass in hydrodynamical simulations of the hierarchical formation of cosmological structures. We consider a standard two-component fl…
