Sanderson et al. look at XMM and Chandra observations of Abell 478. Chandra continuum kT is higher than that from XMM - this effect is minimized if isothermal regions are chosen indicating difference is due to spatial variations in temperature and the different spectral responses of the instruments. They find four hot spots which they interpret as shock-heating due to the radio source in the cluster center.

Cassano & Brunetti calculate thermal and non-thermal emission from clusters using an evolutionary model.

Georgantopoulos & Georgakakis find no evidence of X-ray absorption in an XMM sample XBONGs.

Mauche et al. discuss Fe-L shell diagnostics and identify density diagnostics.

Keywords: papers, clusters, AGN, X-ray spectroscopy
