X-ray Substructure Studies of Four Galaxy Clusters using XMM-Newton Data

Yu-Ying Zhang, Thomas H Reiprich, Alexis Finoguenov +2

Mahdavi et al. find that the degree of agreement between weak lensing and X-ray mass measurements is a function of cluster radius. Numerical simulations also point out that X-ray m…

X-ray Detection of the Proto Supermassive Binary Black Hole at the Centre of Abell 400

Daniel S. Hudson, Thomas H. Reiprich, Tracy E. Clarke +1

We report the first X-ray detection of a proto-supermassive binary black hole at the centre of Abell 400. Using the Chandra ACIS, we are able to clearly resolve the two active gala…

Studying the Nature of Dark Energy with Galaxy Clusters

Thomas H. Reiprich, Daniel S. Hudson, Thomas Erben +1

We report on the status of our effort to constrain the nature of dark energy through the evolution of the cluster mass function. Chandra temperature profiles for 31 clusters from a…

Diffuse Non-thermal X-ray Emission: Evidence for Cosmic-ray Acceleration at the Shock Front in IC1262

Daniel S. Hudson, Mark J. Henriksen

We report the first localization of diffuse, non-thermal, X-ray emission from a nearby galaxy cluster. Using Chandra data, we have isolated a diffuse non-thermal X-ray component wi…

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…

A BeppoSAX Observation of the IC1262 Galaxy Cluster

D. S. Hudson, M. J. Henriksen, S. Colafrancesco

We present an analysis of BeppoSAX observations of the IC1262 galaxy cluster and report the first temperature and abundance measurements, along with preliminary indications of diff…
