项目摘要
The main subject of this research is to investigate the energy source of the interstellar clouds by observing far-infrared continuum emisison from the interstellar dust grains.First, an eight-element far-infrared linear array detector was newly developed for mapping an wide area of the sky with higher efficiency. This new array achieved the highest responsivity and the pixel size of the linear array. An off-axis telescope was manufactured in order to reduce the instrumental infrared emission which is the dominant noise source. The detector and the telescope were mounted on a balloon gondola that has an attitudde control system and other HK functions.The balloon telescope system was flown at Sanriku Ballon Center on September 6,1993. This experiment was successfull in obtaining a far-infrared continuum map of the Galactic plane in 20-45 degree in longitude. The center wavelength was 160 micron and the spatial resolution was 6 arcminute. This wavelength had not been covered by IRAS and the COBE 160 micron map has only 0.7 degree resolution. Therefore, the 160 micron map taken by this observatiton is a unique data.Analysing the data, we found the fact that the temperature of the interstellar dust grain in the Galactic plane is nearly uniform in 0.1 degree scale, which suggests that the dust grain distributes uniformely rather than near-by the energy source. This conclusion agrees to that obtained from the [CII] line intensity map taken by us.
本研究的主要目的是通过观测星际尘埃颗粒的远红外连续辐射来研究星际云的能量来源。首先,我们研制了一种新的八元远红外线阵探测器,用于更高效率地测绘大范围的天空。这种新阵列实现了线性阵列的最高响应度和像素尺寸。制造了一个离轴望远镜,以减少仪器红外辐射,这是主要的噪声源。探测器和望远镜安装在一个带有姿态控制系统和其他HK功能的气球吊舱上,该气球望远镜系统于1993年9月6日在三陆气球中心飞行。这次实验成功地获得了银道面在经度20-45度范围内的远红外连续谱图。中心波长为160微米,空间分辨率为6弧分。这个波长没有被IRAS覆盖,COBE 160微米的地图只有0.7度的分辨率。通过对这些数据的分析,我们发现,在0.1度尺度上,星际尘埃颗粒在银道面内的温度几乎是均匀的,这表明尘埃颗粒分布是均匀的,而不是在能量源附近。这一结论与我们从[CII]线强度图上得到的结论是一致的。
