银河系磁场全球模拟研究进展

Progress in the Global Modeling of the Galactic Magnetic Field

Michael Unger, Glennys Farrar

摘要:

本文讨论了银河系磁场(GMF)性质的全球模型。在一项分析中,研究了Jansson & Farrar(2012)(JF12)的GMF模型的几个改进和变化,该分析受到河外源的全天旋转测量以及WMAP和Planck的偏振和非偏振同步辐射数据的约束。我们介绍了所研究的模型变化对银河系中超高能宇宙射线传播的影响。

英文摘要:

We discuss the global modeling of the properties of the Galactic Magnetic Field (GMF). Several improvements and variations of the model of the GMF from Jansson & Farrar (2012) (JF12) are investigated in an analysis constrained by all-sky rotation measures of extragalactic sources and polarized and unpolarized synchrotron emission data from WMAP and Planck. We present the impact of the investigated model variations on the propagation of ultrahigh-energy cosmic rays in the Galaxy.
