摘要:

朱雀观测了人马座A* 东南约20'处射电弧附近的银河系中心区域。在18'x18'的视野中,我们发现了四个不同的X射线源:一颗明亮的恒星和一个与软带星团有关的漫射源(0.5-2.0 keV),一个高能带(4-6 keV)的小团簇和一个6.4 keV谱带的特殊团簇,后两个团簇位于射电弧的南端。本文报告的结果,并讨论了这些X射线源的起源,特别强调小团块。

英文摘要:

Suzaku observed the Galactic center region near the Radio Arc at ~20' southeast of Sagittarius A*.In the 18'x18' field of view, we found four distinct X-ray sources: a bright star and a diffuse source associated with the star clusters in the soft band (0.5-2.0 keV), a small clump in a higher energy band (4-6 keV), and a peculiar clump in the 6.4 keV line band.The latter two clumps are located at the south end of the Radio Arc. This paper reports on the results, and discusses the origin of these X-ray sources, with a particular emphasis on small clumps.
