Spectrum composition of galactic center X-ray emission with point and diffuse X-ray sources.

NOBUKAWA M. and KOYAMA K.

Abstract (from CDS):

This paper reports that the X-ray spectrum from the Galactic Center X-ray Emission (GCXE) is expressed by an assembly of active binaries, non-magnetic cataclysmic variables, magnetic cataclysmic variables (X-ray active stars: XASs), cold matter, and diffuse sources. In the fitting of the limited components of the XASs, the GCXE spectrum exhibits significant excesses with χ2/d.o.f. = 5.67. The excesses are found at the energies of Kα, Heα, Lyα, and the radiative recombination continuum of S, Fe, and Ni. By adding components of the cold matter and the diffuse sources, the GCXE spectrum is nicely reproduced with χ2/d.o.f. = 1.53, which is the first quantitative model for the origin of the GCXE spectrum. The drastic improvement is mainly due to the recombining plasmas in the diffuse sources, which indicate the presence of high-energy activity of Sgr A* in the past of >1000 yr.
