The Time-Variable Ultra-Luminous X-ray Sources of "The Antennae"
G. Fabbiano, A. Zezas, A. R. King +3
We report the first results of the Chandra temporal monitoring of the ultra-luminous X-ray sources (ULXs) in the Antennae galaxies (NGC 4038/39). Observations at four different epo…
The morphology-density relation in X-ray bright galaxy groups
Stephen F. Helsdon, Trevor J. Ponman
We have examined the morphological make-up of X-ray bright groups. The brighter galaxies in these groups exhibit clear morphology-density and morphology-radius relations. The group…
X-ray bright groups and their galaxies
Stephen F. Helsdon, Trevor J. Ponman
Combining X-ray data from the ROSAT PSPC and optical data drawn from the literature, we examine in detail the relationship between the X-ray and optical properties of X-ray bright…
The detection of diffuse emission in HCG 16 with XMM-Newton
E. Belsole, L. Sauvageot, T. J. Ponman +1
We report results obtained from analysis of the XMM-Newton observation of the compact group of galaxies HCG 16. It is a peculiar system composed of 7 spirals, 6 of which are active…
ASCA observations of groups at radii of low overdensity. Implications for the cosmic preheating
A. Finoguenov, C. Jones, H. Boehringer +1
Through a 3d-modeling of ASCA observations, we performed a spatially resolved X-ray spectroscopic study, extending to radii exceeding 150 kpc, for a sample of 9 groups of galaxies.…
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…
