Radio Astronomical Studies of the Diffuse Interstellar Medium

卡尔·海尔斯博士将继续主要使用射电天文技术对星际扩散介质进行广泛的研究。他将继续对21厘米中性氢线的塞曼分裂进行广泛的观测，集中在感兴趣区域的广泛地图上；尝试测量18厘米氢线的线偏振；通过绘制21厘米线和漫射复合线的详细地图，研究大型星际壳和超壳层的形态和运动学；通过对现有数据的深入分析，研究中性星际介质的基本拓扑结构；盲目搜索异常速度特征，例如可能是由于壳层的快速膨胀；通过在银河系平面进行大规模调查，研究扩散射电复合线发射和温暖电离介质的全球性质；通过使用分子和光学发射线对电离氢区中的球体进行全面和详细的调查；确认可能探测到327兆赫的重氢谱线；并开始搜索310兆赫的重氢氢气谱线。

Dr. Carl Heiles will continue his wide ranging investigations of the diffuse interstellar medium primarily using radio astronomical techniques. He will continue extensive observations of Zeeman splitting of the 21-cm neutral hydrogen line, concentrating on extensive maps of interesting regions; attempt the measurement of linear polarization of the 18-cm lines of hydroxyl; study the morphology and kinematics of large interstellar shells and supershells by detailed mapping of the 21-cm line and diffuse radio recombination lines; investigate the fundamental topology of the neutral interstellar medium by intensive analysis of existing data; perform a blind search for anomalous velocity features, such as may be due to rapidly expanding shells; investigate the global properties of the diffuse radio recombination line emission and the Warm Ionized Medium by performing a large survey in the Galactic plane; perform a comprehensive and detailed investigation of globules in ionized hydrogen regions by using both molecular and optical emission lines; confirm a possible detection of the 327 MHz line of deuterium; and launch a search for the 310 MHz lines of deuterated hydroxyl.
