Abstract: Located ∼ 100 pc from the dynamic center of the Milky Way, the molecular cloud Sagittarius B2 (Sgr B2) is the most massive such object in the Galactic Center region. In X-rays, Sgr B2 shows a prominent neutral Fe Kα line at 6.4 keV and continuum emission beyond 10 keV, indicating highenergy, non-thermal processes in the cloud. The Sgr B2 complex is an X-ray reflection nebula whose total emissions have continued to decrease since the year 2001 as it reprocesses what are likely one or more past energetic outburs… Show more

“…This value is slightly larger than that obtained by Terrier et al (2010). It is worth noting that the decrease in the Sgr B2 hard X-ray continuum observed by INTEGRAL is in agreement with the overall drop of the 6.4 keV line flux measured by XMM-Newton in the same sky region (Rogers et al 2021). This indicates that the Fe K line flux and the hard X-ray continuum are linked to each other, confirming the reflection scenario.…”
