Scientific paper

Recently it has been discovered that the Fe Ka line fluxes from Molecular Clouds (MCs) close to Sgr A* show a pattern of variability that can be closely matched to that measured from Sgr B2, the prototype X-ray Refection nebula (XRN) in the GC region. The whole picture might be compatible with a period of increased activity of Sgr A* about 100 years ago, as a common origin for the fluorescent Fe K emission from MCs in the central molecular zone (CMZ). However, this idea must still be definitively confirmed. For this reason, we apply for a 50 ksec observation of the peculiar Sgr D giant MC, which is the only one in the CMZ that has not yet shown 6.4 keV emission associated with XRN photoionization.
