使用NASA的柯伊伯机载天文台（KAO），我们在银河系中心的不寻常的HII区域Sgr A West测量了[SIII] 19和33µ m，[Felli] 23µm，[OIII] 52和88µm，[NIII] 57 µm以及[NII] 122和205µmarising的线条。的排放是一致的低密度（~1000 cm-3）腔气体的光电离，但N+的排放可能主要出现在较高密度的“迷你螺旋”电离流光在我们的光束中未解决。
Using NASA’s Kuiper Airborne Observatory (KAO), we have measured lines of [SIII] 19 and 33µm, [Felli] 23µm, [OIII] 52 and 88µm, [NIII] 57 µm, and [NII] 122 and 205µmarising in the unusual HII region Sgr A West at the Galactic Center. The emission is consistent with photoionization of the low density (~1000 cm-3) cavity gas, but the N+emission could arise predominantly in the higher density “mini-spiral” ionized streamers unresolved in our beam.
