Chandra X-Ray Detection of the Radio Hotspots of 3C295
D. E. Harris, P. E. J. Nulsen, T. P. Ponman +17
An observation of the radio galaxy 3C295 during the calibration phase of the Chandra X-ray Observatory reveals X-ray emission from the core of the galaxy, from each of the two prom…
Multi-wavelength observations of an evolved galaxy group: An endpoint of galaxy merging?
L. R. Jones, T. J. Ponman, Duncan A. Forbes
The group of galaxies RXJ1340.6+4018 has approximately the same bolometric X-ray luminosity as other bright galaxy groups and poor clusters such as the Virgo cluster. However, 70%…
Galaxies in Clusters: the Observational Characteristics of Bow-Shocks, Wakes and Tails
Ian R. Stevens, David M. Acreman, Trevor J. Ponman
The dynamical signatures of the interaction between galaxies in clusters and the intracluster medium (ICM) can potentially yield significant information about the structure and dyn…
An ASCA Study of the Heavy Element Distribution in Clusters of Galaxies
A. Finoguenov, L. P. David, T. J. Ponman
We perform a spatially resolved X-ray spectroscopic study of a set of 11 relaxed clusters of galaxies observed by the ROSAT/PSPC and ASCA/SIS. Using a method which corrects for the…
On The Relationship Between Age and Dynamics in Elliptical Galaxies
Duncan A. Forbes, Trevor J. Ponman
Here, using a sample of 88 galaxies, we examine the scatter about the Faber-Jackson (F-J) relation, and find that a galaxy's position relative to this relation depends on its age.…
Constraining the Role of SN Ia and SN II in Galaxy Groups by Spatially Resolved Analysis of ROSAT and ASCA Observations
A. Finoguenov, T. J. Ponman
We present the results of modelling the distribution of gas properties in the galaxy groups HCG51, HCG62 and NGC5044, and in the poor cluster AWM7, using both ASCA SIS and ROSAT da…
