Pointing 1: Sgr A
SMBH Sgr A*
Persistent 1033 ergs s-1
 Too faint
Flare Max 1035-36 ergs s-1
 Can detect
XRS

Fe
Thermal
1kT (CIE)!!
Sgr A East: MM SNR (W49B Type?)
A SNR at 20” offset from A*
Strong Fe- K (EW~3keV)
 Line dynamics & plasma diagnostics with XRS
(Plasma motion, & age？)

Sgr B2 Ｘ線反射星雲
外部のＸ線源に照らされて蛍光で輝いている
 中心核の過去の活動性？
Cloud velocity, Compton scattered line  照射源特定

line center ±0.3 eV
line width ±0.4 eV
Compton ±10 eV
Pointing 3: Radio Arc
⇒ Thermal + 中性鉄輝線
⇒ non-thermal
⇒ 中性鉄輝線
Radio Arc SNR? Shock? XRN?
色々な放射が混在

Pointing 4: Sgr C
電波のfilamentの絵
XRN? + radio filament
filament  shock加速？
XRN  Sgr B2と対照的な位置で中心核起源か
どうか探るのに重要
Plasma
plasma motion  negative longitudeも見るのが重要
