论文摘要
该评论专门研究了Alves等人最近发现的Radcliffe Wave。根据分子云的分析。这些作者挑出了一条狭窄的分子云链，几乎在一条线上伸长，位于银河轴约30 $^o $的倾斜度。 Radcliffe Wave本身描述了分子云的垂直垂直振荡，最大振荡幅度约为160 PC，特征波长约为2.5 kpc。迄今为止，在a）垂直分布中已经确认了radcliffe波的存在，b）Maser辐射的源和无线电星的来源，它们是非常年轻的恒星和与分子云密切相关的固有恒星，c）T tau型的低质量恒星，d）t tau型的低质量，d）更多的巨大ob和e）更年轻的恒星。拉德克利夫（Radcliffe）波也被追溯到年轻恒星的垂直速度。大多数对各种年轻恒星垂直速度的分析的考虑结果表明，Radcliffe波中恒星的垂直位置和垂直速度的振荡同步发生。 Radcliffe波的性质尚不清楚。大多数研究人员将其发生与对前锋的银河系磁盘（例如银河系的矮人星系）的银河系磁盘产生外部重力影响相关联。
The review is devoted to the Radcliffe Wave recently discovered by Alves et al. from the analysis of molecular clouds. These authors singled out a narrow chain of molecular clouds, elongated almost in one line, located at an inclination of about 30$^o$ to the galactic axis y. The Radcliffe Wave itself describes damped vertical oscillations of molecular clouds with a maximum oscillation amplitude of about 160 pc and a characteristic wavelength of about 2.5 kpc. To date, the presence of the Radcliffe Wave has been confirmed in the vertical distribution of a) interstellar dust, b) sources of maser radiation and radio stars, which are very young stars and protostars closely associated with molecular clouds, c) low-mass stars of the T Tau type, d) more massive OB stars and e) young open clusters of stars. The Radcliffe Wave is also traced in the vertical velocities of young stars. Most of the considered results of the analysis of the vertical velocities of various young stars show that the oscillations of the vertical positions and vertical velocities of stars in the Radcliffe Wave occur synchronously. The nature of the Radcliffe Wave is completely unclear. The majority of researchers associate its occurrence with the assumption of an external gravitational impact on the galactic disk of a striker such as a dwarf satellite galaxy of the Milky Way.
