Evolution of the X-ray Properties of Clusters of Galaxies
J. Patrick Henry
The amount and nature of the evolution of the X-ray properties of clusters of galaxies provides information on the formation of structure in the universe and on the properties of t…
X-ray Properties of High Redshift Clusters
J. Patrick Henry
We describe the ensemble X-ray properties of high redshift clusters with emphasis on changes with respect to the local population. Cluster X-ray luminosity evolution is detected in…
Cluster X-ray Luminosity Evolution
J. Patrick Henry
Whether the X-ray luminosities of clusters of galaxies evolve has been a contentious issue for over ten years. However, the data available to address this issue have improved drama…
MACS: The evolution and properties of massive clusters of galaxies
Harald Ebeling, Alastair Edge, J. Patrick Henry
We present first results from the MAssive Cluster Survey (MACS), a new large-scale X-ray survey designed to find and characterize very massive, distant clusters of galaxies. Based…
An X-ray Temperature Map of Coma
Ulrich G. Briel, J. Patrick Henry
We present an X-ray temperature map of the Coma cluster of galaxies obtained with the ROSAT PSPC. As expected from the X-ray surface brightness distribution the intracluster gas of…
Discovery of a Large Gravitational Arc in the X-ray Cluster A2280
I. M. Gioia, J. P. Henry, G. A. Luppino +6
This Letter presents the serendipitous discovery of a large arc in an X-ray selected cluster detected in the Rosat North Ecliptic Pole (NEP) survey. The cluster, associated with Ab…
