Abstract:
The Sgr B2 giant molecular cloud is claimed to be an ''X-ray
reflection nebula'' - the reprocessing site of a powerful flare of
the Sgr A* source, occurred few hundred years ago. The shape of the
X-ray spectrum and the strength of the iron fluorescent line support
this hypothesis. We argue that the most clean test of the origin of
X-rays from Sgr B2 would be a detection of polarized
emission from this source.
