Shock heating in the group atmosphere of the radio galaxy B2 0838+32A
Nazirah N. Jetha, Martin J. Hardcastle, Trevor J. Ponman +1
We present Chandra and radio observations, and analysis of Sloan Digital Sky Survey data, of the radio galaxy B2 0838+32A (4C 32.26) and its environment. The radio galaxy is at the…
3C 40 in Abell 194: can tail radio galaxies exist in a quiescent cluster?
I. Sakelliou, M. J. Hardcastle, N. N. Jetha
The nearby cluster Abell 194 hosts two luminous, distorted radio galaxies. Both reside within the cluster's core region, being separated in projection by only 100 kpc. It is often…
The XMM-Newton wide-field survey in the COSMOS field: VI. Statistical properties of clusters of galaxies
A. Finoguenov, L. Guzzo, G. Hasinger +30
We present the results of a search for galaxy clusters in the first 36 XMM-Newton pointings on the COSMOS field. We reach a depth for a total cluster flux in the 0.5-2 keV band of…
A wide angle tail radio galaxy in the COSMOS field: evidence for cluster formation
V. Smolcic, E. Schinnerer, A. Finoguenov +19
We have identified a complex galaxy cluster system in the COSMOS field via a wide angle tail (WAT) radio galaxy consistent with the idea that WAT galaxies can be used as tracers of…
XMM-Newton observations of Abell 2255 : a test case of a merger after `core-crossing'
Irini Sakelliou, Trevor J. Ponman
It has been known that Abell 2255 is not a relaxed cluster, but it is undergoing a merger. Here, we report on the analysis of the XMM-Newton observations of this cluster. The X-ray…
The cool wake around 4C 34.16 as seen by XMM-Newton
I. Sakelliou, D. M. Acreman, M. J. Hardcastle +3
We present XMM-Newton observations of the wake-radiogalaxy system 4C34.16, which shows a cool and dense wake trailing behind 4C34.16's host galaxy. A comparison with numerical simu…
