Heating versus Cooling in Galaxies and Clusters of Galaxies
Proceedings of the MPA/ESO/MPE/USM Joint Astronomy Conference held in Garching, Germany, 6-11 August 2006
Article
Early-type galaxies (ETGs) contain most of the stars present in the local Universe and, above a stellar mass content of ~5 × 1010 solar masses, vastly outnumber spiral galaxies such as the Milky Way. These massiv...

Chapter and Conference Paper
For the spectral determination of the temperature distribution in galaxy clusters we developed a double background subtraction method, and applied it to 2 morphology unbiased samples of X-ray luminous galaxy c...
Chapter and Conference Paper
Known as the closest cooling-core hosting an active nucleus, M87 is among the best candidates for detailed studies of the mechanisms behind the heating versus cooling balance. The deepest XMM-Newton observatio...
Chapter and Conference Paper
XMM-Newton observations of the outskirts of the Coma cluster of galaxies confirm the existence of warm X-ray gas claimed previously and provide a robust estimate of its temperature (~ 0.2 keV) and oxygen abund...
Article
We describe measurements of the mirror vignetting in the XMM-Newton Observatory made in-orbit, using observations of SNR G21.5-09 and SNR 3C58 with the EPIC imaging cameras. The instrument features that compli...
