摘要:

测量谱线的塞曼分裂-发射和吸收-可以直接估计原子和分子云的磁场强度和方向,无论是在我们自己的银河系还是在外部星系。这种方法将探测星际介质的温暖和寒冷中性成分中的磁场,为计划探测电离成分中的磁场的广泛SKA法拉第研究提供补充。

英文摘要:

The measurement of Zeeman splitting in spectral lines---both in emission and absorption---can provide direct estimates of the magnetic field strength and direction in atomic and molecular clouds, both in our own Milky Way and in external galaxies. This method will probe the magnetic field in the warm and cold neutral components of the interstellar medium, providing a complement to the extensive SKA Faraday studies planning to probe the field in the ionized components.
