Jet-X - Extended sources

The study of extended sources will be a very important aspect of Jet-X because of its good point response. Previous hard X-ray mission such as GINGA had no spatial information at all, and the one mission which did (ASCA) had a very poor spatial response. An example of extended sources are clusters of galaxies, which groups of galaxies which are gravitationally bound together. Figure 1 shows the Coma cluster observed with ROSAT showing the hot (50 million) degree gas that pervades the cluster. Jet-X will be able to observe clusters of galaxies withthe same spatial resolution as ROSAT, but because of Jet-X's better spectral resolution and larger spectral coverage will be able to investigate the nature of the intercluster gas to a higher degree of accuracy.
