Abstract
We present an X-ray temperature map of the Coma cluster of galaxies obtained with the ROSAT PSPC. As expected from the X-ray surface brightness distribution the intracluster gas of Coma is not isothermal. The temperature structure resembles a bow shock of hot gas produced by the passage of the subcluster around NGC 4839 through the main cluster, confirming hydrodynamical simulations.
