6. Conclusions

The analysis of the diffuse emission from the GC region reveals the presence of at least two distinct components: a soft one (T_mekal 0.6 keV), spatially correlated with the SgrA East radio halo and a hard component (T_mekal 8-9 keV). While the hard component is elongated along the Galactic Plane and does not spatially correlate with physical structures observed at other wavelengths, the spatial distribution of the soft component is remarkably well correlated with the triangular radio halo of SgrA East. The parameters derived for the softer component match extremely well with the idea that this thermal X-ray emission is due to a SNR origin for the SgrA East halo.
