Infrared extinction toward the Galactic Centre

We derive the extinction curve toward the Galactic center (GC) from 1 to 19um. We use hydrogen emission lines of the minispiral observed by ISO-SWS and SINFONI. The...我们推导了银心（Galactic center, GC）方向1至19微米波段的消光曲线（extinction curve）。我们利用了ISO-SWS与SINFONI观测得到的微旋臂（minispiral）的氢发射线。The...
