Chandra Observation of RXJ1720.1+2638: a Nearly Relaxed Cluster with a Fast Moving Core?
P. Mazzotta, M. Markevitch, A. Vikhlinin +3
We have analyzed the Chandra observation of the distant (z=0.164) galaxy cluster RXJ1720.1+2638 in which we find sharp features in the X-ray surface brightness on opposite sides of…
A High Resolution Study of the Hydra A Cluster with Chandra: Comparison of the Core Mass Distribution with Theoretical Predictions and Evidence for Feedback in the Cooling Flow
L. P. David, P. E. J. Nulsen, B. R. McNamara +5
The cooling flow cluster Hydra A was observed during the orbital activation and calibration phase of the Chandra Observatory. While the X-ray image of the cluster exhibits complex…
Chandra Observation of Abell 2142: Survival of Dense Subcluster Cores in a Merger
M. Markevitch, T. J. Ponman, P. E. J. Nulsen +19
We use Chandra data to map the gas temperature in the central region of the merging cluster A2142. The cluster is markedly nonisothermal; it appears that the central cooling flow h…
