不规则星系中的磁场

Magnetic Fields in Irregular Galaxies

摘要:

磁场是星际介质的重要组成部分,特别是在低质量星系中,如不规则星系,磁压可能很大。然而,很少有不规则星系观测到磁场结构。利用VLA、GBT和ATCA,我们观测了几个射电连续谱中的不规则星系,以确定它们的磁场结构。在这里,我们报告了我们对星系NGC 4214和NGC 1569的研究结果。

英文摘要:

Magnetic fields are an important component of the interstellar medium, especially in low-mass galaxies like irregulars where the magnetic pressure may be significant. However, few irregular galaxies have observed magnetic field structures. Using the VLA, the GBT, and the ATCA, we have observed several irregular galaxies in the radio continuum to determine their magnetic field structures. Here we report on our results for the galaxies NGC 4214 and NGC 1569.
