On the Temperature and Intensity Distribution of the Galactic X-ray Plasma

Abstract
We present the results of our investigation of the composition of the diffuse soft X-ray background emission (SXRB). Combining data of the Leiden/Dwingeloo HI Survey and the ROSAT All-Sky Survey (RASS), we set up a radiation transport equation in order to model the SXRB. Two different techniques lead to the model parameters: An image oriented approach which compares observed and modeled maps of the 1/4 and 3/4 keV X-ray energy regime and a more analytic approach using scatter diagrams. The analysis shows that only three independent components of the emitting plasma (local, halo and extragalactic) are needed to explain the SXRB. The results for the temperatures and X-ray intensities, which characterize the three components, are given and compared to an alternative model.
