On the Anomalous Temperature Distribution of the Intergalactic Medium in the NGC 3411 Group of Galaxies
E. O'Sullivan, J. M. Vrtilek, D. E. Harris +1
We present XMM, Chandra and VLA observations of the USGC S152 group and its central elliptical NGC 3411. Imaging of the group X-ray halo suggests it is relaxed with little apparent…
A statistically-selected Chandra sample of 20 galaxy clusters -- I. Temperature and cooling time profiles
Alastair J. R. Sanderson, Trevor J. Ponman, Ewan O'Sullivan
We present an analysis of 20 galaxy clusters observed with the Chandra X-ray satellite, focussing on the temperature structure of the intracluster medium and the cooling time of th…
X-ray observations of three young, early-type galaxies
A. E. Sansom, E. O'Sullivan, Duncan A. Forbes +2
Massive halos of hot plasma exist around some, but not all elliptical galaxies. There is evidence that this is related to the age of the galaxy. In this paper new X-ray observation…
