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…
New Results from Chandra
W. Forman, M. Markevitch, C. Jones +2
We discuss two themes from Chandra observations of galaxies and clusters. First, we describe the effects of radio-emitting plasmas or ``bubbles'', inflated by active galactic nucle…
A Textbook Example of a Bow Shock in the Merging Galaxy Cluster 1E0657-56
M. Markevitch, A. H. Gonzalez, L. David +5
The Chandra image of the merging, hot galaxy cluster 1E0657-56 reveals a bow shock propagating in front of a bullet-like gas cloud just exiting the disrupted cluster core. This is…
Chandra Observation of MS 1455.0+2232: cold fronts in a massive cooling flow cluster?
P. Mazzotta, M. Markevitch, W. R. Forman +3
We present the Chandra observation of the cluster of galaxies MS 1455.0+2232. From previous ASCA and ROSAT observations, this cluster was identified as a ``relaxed'' cluster that h…
Constraining H0 from Chandra Observations of Q0957+561
G. Chartas, V. Gupta, G. Garmire +4
We report the detection of the lens cluster of the gravitational lens (GL) system Q0957+561 from a deep observation with the Advanced CCD Imaging Spectrometer on-board the Chandra…
Chandra Observations of NGC 4636 - An Elliptical Galaxy in Turmoil
C. Jones, W. Forman, A. Vikhlinin +5
Chandra images show symmetric, 8 kpc long, arm-like features in the X-ray halo surrounding NGC 4636. The leading edges of these features are sharp and are accompanied by temperatur…
Zooming in on the Coma Cluster with Chandra: Compressed Warm Gas in the Brightest Cluster Galaxies
A. Vikhlinin, M. Markevitch, W. Forman +1
The Chandra image of the central region of the Coma cluster reveals that both its dominant galaxies, NGC4874 and NGC4889, retain the central parts of their X-ray gas coronae. The i…
Chandra X-ray observations of the 3C295 cluster core
S. W. Allen, G. B. Taylor, P. E. J. Nulsen +7
We examine the properties of the X-ray gas in the central regions of the distant (z=0.46), X-ray luminous cluster of galaxies surrounding the powerful radio source 3C 295, using ob…
Chandra Observations of the Gravitationally Lensed System 2016+112
G. Chartas, M. Bautz, G. Garmire +2
An observation of the gravitationally lensed system 2016+112 with the Chandra X-ray Observatory has resolved a mystery regarding the proposed presence of a dark matter object in th…
