银道面附近的磁场结构

Magnetic Field Structure near the Galactic Plane

R. Andreasyan, S. Balayan, V. Movsisyan

摘要:

我们把银河系平面分量磁场的两幅彩色图放在坐标(R;l)和(DM;l)中。结果表明,磁场在邻近的旋臂中具有方向反转,与已知的银河系磁场模型一致。然而,对于人马座旋臂区域,与标准磁场模型存在一些分歧。主要的差异是在人马臂区域,银河系南半球的磁场与北半球的磁场方向相反。我们认为,人马座旋臂,也就是磁旋臂,在这个区域是不对称的银河平面,并主要位于北半球。

英文摘要:

We bring the two color maps for the plane component magnetic field of our Galaxy in coordinates of (R;l) and (DM;l). It was shown that magnetic field has reversals of the direction in neighbor spiral arms, in agreement with known models for the Galactic magnetic field. For the Sagittarius spiral arm region there is, however, some disagreement with standard magnetic field models. The major discrepancy is the fact that in the Sagittarius arm region the magnetic field in Southern hemisphere of the Galaxy, have opposite direction to the field of the Northern hemisphere. We think that the Sagittarius spiral arm, at last the magnetic spiral arm in this region is not symmetric to the Galactic plane, and is located mainly in Northern hemisphere.
