AGN heating in galaxy groups: A statistical study
N. N. Jetha, T. J. Ponman, M. J. Hardcastle +1
We present gas temperature, density, entropy and cooling time profiles for the cores of a sample of 15 galaxy groups observed with {\it Chandra}. We find that the entropy profiles…
The effects of similarity breaking on the intracluster medium
E. J. Lloyd-Davies, R. G. Bower, T. J. Ponman
We construct a family of simple analytical models of galaxy clusters at the present epoch and compare its predictions with observational data. We explore two processes that break t…
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%…
ROSAT Observations of the Galactic Wind in M82
Dave Strickland, Trevor Ponman, Ian Stevens
We present {\em ROSAT} PSPC and HRI observations of the galactic wind from the starburst galaxy M82. \mbox{X-ray} emission from the wind is detected to a distance of $\sim6\kpc$ fr…
EUV Emission from Normal Galaxies
A. M. Read, T. J. Ponman
Using data from the ROSAT Wide Field Camera all-sky survey, we have established upper limits to the extreme ultraviolet (EUV) flux from a sample of 30 bright, nearby, non-active sp…
