X-ray Supercavities in the Hydra A Cluster and the Outburst History of the Central Galaxy's Active Nucleus
M. W. Wise, B. R. McNamara, P. E. J. Nulsen +2
A 227 ksec Chandra Observatory X-ray image of the hot plasma in the Hydra A cluster has revealed an extensive cavity system. The system was created by a continuous outflow or a ser…
AGN Heating through Cavities and Shocks
P. E. J. Nulsen, C. Jones, W. R. Forman +5
Three comments are made on AGN heating of cooling flows. A simple physical argument is used to show that the enthalpy of a buoyant radio lobe is converted to heat in its wake. Thus…
Interaction of Radio Lobes with the Hot Intracluster Medium: Driving Convective Outflow in Hydra A
P. E. J. Nulsen, L. P. David, B. R. McNamara +3
The radio lobes of Hydra A lie within cavities surrounded by a rim of enhanced X-ray emission in the intracluster gas. Although the bright rim appears cooler than the surrounding g…
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…
