The X-ray diffuse emission from the Galactic Center.

SIDOLI L. and MEREGHETTI S.

Abstract (from CDS):

A long BeppoSAX observation of the Galactic Center region shows that the spectrum of the diffuse X-ray emission from the SgrA Complex can be described with the sum of two thermal plasma models with temperatures of ∼0.6keV and ∼8-9keV. 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<5keV) are remarkably well correlated with the triangular radio halo of SgrA East. The parameters derived for the soft component support the interpretation of the SgrA East shell in terms of an evolved supernova remnant.
