中德银道面6厘米偏振巡天综述
The sino-german 6cm polarization survey of the galactic plane: A summary
摘要:
我们用乌鲁木齐25米射电望远镜完成了银道面的6厘米偏振测量。它覆盖了银河经度10度<l<230度,银河纬度|b| <5度。新的偏振图不仅揭示了扩散磁化的星际介质的新特性,而且对于研究单个物体(如Hii区域)非常有用,Hii区域可能充当法拉第屏幕,内部具有强大的规则磁场,以及超新星遗迹的偏振特性和光谱。高灵敏度的调查使我们能够发现两个新的SNRs G178.2-4.2和G25.3-2.1和一些Hii区域。
英文摘要:
We have finished the 6cm polarization survey of the Galactic plane using the Urumqi 25m radio telescope. It covers 10deg<l<230deg in Galactic longitude and |b| <5deg in Galactic latitude. The new polarization maps not only reveal new properties of the diffuse magnetized interstellar medium, but also are very useful for studying individual objects such as Hii regions, which may act as Faraday screens with strong regular magnetic fields inside, and supernova remnants for their polarization properties and spectra. The high sensitivity of the survey enables us to discover two new SNRs G178.2-4.2 and G25.3-2.1 and a number of Hii regions.
