John Dickey University of Minnesota Dr. John Dickey will carry out a spectral line survey of the atomic hydrogen line near 21-cm wavelength from the 4th quadrant of the Galaxy. The survey will be conducted using radio astronomy facilities in Australia, and colleagues in Australia will collaborate with Dr. Dickey. This survey represents a great advance in angular resolution and sensitivity over existing data sets. The observations should dramatically improve our understanding of the distribution and kinematics of the atomic gas component of our Galaxy. Accompanying observations of the radio continuum emission should significantly advance our understanding of the detected ionized hydrogen regions, supernova remnants, and the Galactic magnetic field structure.

约翰·迪基博士将对银河系第四象限21厘米波长附近的氢原子谱线进行谱线测量。这项调查将利用澳大利亚的射电天文设施进行，澳大利亚的同事将与迪基博士合作。与现有数据集相比，这次调查在角度分辨率和灵敏度方面取得了巨大进步。这些观测结果将极大地提高我们对银河系原子气体成分分布和运动学的理解。伴随的射电连续辐射的观测将极大地促进我们对探测到的电离氢区、超新星遗迹和银河系磁场结构的理解。
