Radio Astronomical Studies of the Diffuse Interstellar Medium

卡尔·海勒斯博士将主要利用射电天文技术继续他对漫射星际介质的广泛研究。他将继续对21厘米中性氢线的塞曼分裂进行广泛的观察，并将重点放在有趣区域的广泛地图上；尝试测量羟基18cm线的线极化；通过21厘米线和漫射无线电复合线的详细测绘，研究了大型星际壳层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；对异常速度特征进行盲搜索，例如可能是由于壳层快速膨胀造成的；通过在银道面进行大规模观测，研究了漫射无线电复合线发射和热电离介质的全局特性；利用分子和光学发射谱线对电离氢区域的小球进行全面和详细的研究；确认可能探测到327兆赫的氘谱线；并开始搜索310mhz的氘化羟基谱线。

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.
