Abstract:
A long BeppoSAX observation of the Galactic Center region shows that
the spectrum of the diffuse X-ray emission from the Sgr A Complex can
be described with the sum of two thermal plasma models with
temperatures of ~0.6 keV and ~8-9 keV.  The spatial distribution of
the diffuse emission is energy dependent.  While the hard X-ray
emission has a nearly symmetric distribution elongated along the
Galactic Plane, the soft X-rays (E < 5 keV) are remarkably well
correlated with the triangular radio halo of SgrA East. The parameters
derived for the soft component support the interpretation of the Sgr A
East shell in terms of an evolved supernova remnant.
