摘要

利用射电连续体和红外表面亮度图，我们调查了星系蠕虫——垂直于星系平面的结构。这是第一次对结构进行解析并确定距离。我们根据射电频谱指数发现了两个主要的类别，并提出了一个进化序列。

Galactic worms: Infrared and radio maps of the first quadrant

Using radio continuum and infrared surface brightness maps we surveyed galactic worms—structures perpendicular to the galactic plane. For the first time, the structures were resolved and distances determined. We find two main classes based on radio spectral index, and suggest an evolutionary sequence.
