6.4 keV Light Curve of Sgr B2 Region

January 25, 2013
This light curve of the 6.4 keV line emission from neutral iron in the Sgr B2 region is composed from archive data of four X-ray missions: September 1994 ASCA (Japan) March 2000 Chandra (NASA) April 2001 XMM-Newton (ESA) July 2001 Chandra (NASA) September 2004 XMM-Newton (ESA) October 2005 Suzaku (Japan) The Sgr B2 region for which the combined light curve was derived by Tatsuya Inui et al. [2008] is outlined in the related image. Two prominent objects in this region, M0.66-0.02 and G0570-0.018, show a similar light curve over the studied period. From the combined X-ray data Tatsuya Inui et al. [2008] arrive at the conclusion that Sgr A*, the black hole at the Galactic centre, caused X-ray fluorecense in these two objects some 300 years after Sgr A* experienced an outburst.
