Temperature Maps of Clusters of Galaxies

We have completed our analysis of the temperature structure of clusters of galaxies. The next to last paper to be supported by this project has been published in the Astrophysical Journal. The analysis for the final paper is nearly complete, but has been delayed by the high priority demands of Chandra Mission Planning and Chandra Calibration which have required more than the expected amount of work by Forman and Donnelly. For this paper, a final check of the 55 member cluster sample identified several clusters for which X-ray luminosities are needed. We also verified the ASCA analysis and the novel method we use for the derivation of the temperature maps against XMM-Newton observations for a few clusters which are publicly available in the XMM-Newton archives We find excellent agreement. This final paper is expected to be submitted by November 2002. It will provide a large, well-defined sample of clusters for comparison to large numerical simulations which can help clarify the evolution of the largest collapsed systems in the Universe.
