We report on a partially circular X-ray surface brightness discontinuity found at about 55 kpc from the centre of Abell 2199 with Chandra X-ray Observatory observations. Unlike cold fronts found in other clusters, the feature shows no significant temperature change across it but has an apparent density jump. We therefore identify it as a weak isothermal shock associated with the central active galactic nucleus and the inflation of its radio bubbles, as found in the Perseus cluster. We examine a…

Shocks and Bubbles in a Deep Chandra Observation of the Cooling Flow Cluster Abell 2052
Abstract : We present results from a deep Chandra observation of Abell 2052. A2052 is a bright, nearby, cooling flow cluster, at a redshift of z = 0.035. Concentric surface brightness discontinuities
Feedback through multiple outbursts in the cluster 2A 0335+096
We examine the core of the X-ray bright galaxy cluster 2A 0335+096 using deep Chandra X-ray imaging and spatially resolved spectroscopy, and include new radio observations. The set of around eight
Feedback in the cores of clusters Abell 3581, 2A 0335+096, and Sersic 159-03
The cores of massive galaxy clusters, where hot gas is cooling rapidly, appear to undergo cycles of self-regulating energy feedback, in which AGN outbursts in the central galaxies episodically
We present new Chandra observations of A2199 that show evidence of gas sloshing due to a minor merger, as well as impacts of the radio source, 3C 338, hosted by the central galaxy, NGC 6166, on the
Probing the Extreme Realm of Active Galactic Nucleus Feedback in the Massive Galaxy Cluster, RX?J1532.9+3021
We present a detailed Chandra, XMM-Newton, Very Large Array (VLA) and Hubble Space Telescope analysis of one of the strongest cool core clusters known, RX?J1532.9+3021 (z = 0.3613). Using new, deep
Thermodynamic perturbations in the X-ray halo of 33 clusters of galaxies observed with Chandra ACIS
In high-resolution X-ray observations of the hot plasma in clusters of galaxies significant structures caused by AGN feedback, mergers, and turbulence can be detected. Many clusters have been
AGN feedback and iron enrichment in the powerful radio galaxy, 4C+55.16
We present a detailed X-ray analysis of 4C+55.16, an unusual and interesting radio galaxy, located at the centre of a cool core cluster of galaxies. 4C+55.16 is X-ray bright (LX(cluster)∼ 1045 erg
A deeper X‐ray study of the core of the Perseus galaxy cluster: the power of sound waves and the distribution of metals and cosmic rays
We make a further study of the very deep Chandra observation of the X-ray brightest galaxy cluster, A 426 in Perseus. We examine the radial distribution of energy flux inferred by the
Search for gas bulk motions in eight nearby clusters of galaxies with Suzaku
To search for bulk motions of the intracluster medium, we analyzed the X-ray spectra taken with the Suzaku satellite and measured the Doppler shift of Fe-K line emission from eight nearby clusters of
Suzaku Constraints on the Soft and Hard Excess Emissions from Abell 2199
The nearby ($z=0.03015$) cluster of galaxies Abell~2199 was observed by Suzaku in X-rays, with five pointings for $\sim 20$ ks each. From the XIS data, the temperature and metal abundance profiles


A very deep Chandra observation of the Perseus cluster: shocks, ripples and conduction
We present the first results from a very deep Chandra X-ray observation of the core of the Perseus cluster of galaxies. A pressure map reveals a clear thick band of high pressure around the inner
A Chandra Study of the Complex Structure in the Core of 2A 0335+096
We present a Chandra observation of the central (r 40 kpc), the X-ray surface brightness is symmetric and slightly elliptical. The cluster has a cool, dense core; the radial temperature gradient
Chandra Observation of Abell 2142: Survival of Dense Subcluster Cores in a Merger
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 has been disturbed
Chandra observations of Abell 2199
We present results from an analysis of two Chandra observations of the rich, nearby galaxy cluster Abell 2199. We find evidence (having corrected for projection effects) for radial gradients in
Chandra X-Ray Spectral Analysis of Cooling Flow Clusters, 2A 0335 $+$ and Abell 2199
We report on a spatially resolved analysis of Chandra X-ray data on a nearby typical cooling flow cluster of galaxies 2A 0335+096, together with A2199 for a comparison. As recently found in the cores
XMM-Newton spectroscopy of the cluster of galaxies 2A 0335+096
We present here the results of a deep (130 ks) XMM-Newton observation of the cluster of galaxies 2A 0335+096. The deep exposure allows us to study in detail its temperature structure and its
Non-thermal X-rays, a high-abundance ridge and fossil bubbles in the core of the Perseus cluster of galaxies
Using a deep Chandra observation of the Perseus cluster of galaxies, we find a high-abundance shell 250 arcsec (93 kpc) from the central nucleus. This ridge lies at the edge of the Perseus radio
