摘要: We carry out a joint spectral analysis of the Cygnus Loop using data from all six detectors combined Suzaku and XMM-Newton. This had not been done before, but if model is physically realistic, it required that be consistent with different instruments. Thus, our results are an important verification models for Loop. One prominent features bright "V" region near southwest rim. choose this region, in part, because has observed by both divide field view into 12 box-shaped regions, such each contains 9000-13,000 photons Suzaku-XIS1 camera. A non-equilibrium ionization variable abundances (VNEI) or two-component VNEI found to fit observations. Resulting electron temperatures timescales inversely related, origin density variations factor ~3. Element temperature strongly correlated, which can explained mixing outer hydrogen-rich envelope ejecta: Heavy-element-rich regions have higher velocity reach far center Loop, resulting shock more element-rich regions.
