Correlations of near-infrared, optical and X-ray luminosity for early-type galaxies
S. C. Ellis, Ewan O'Sullivan
The relation between X-ray luminosity and near-infrared luminosity for early-type galaxies has been examined. Near-infrared (NIR) luminosities should provide a superior measure of…

AWM 4 - an isothermal cluster observed with XMM-Newton
E. O'Sullivan, J. M. Vrtilek, J. C. Kempner +2
We present analysis of an XMM observation of the poor cluster AWM 4. The cluster is relaxed and its X-ray halo is regular with no apparent substructure. Azimuthally averaged radial…
