论文摘要
众所周知,在天体物理环境中,磁水动力学(MHD)的湍流无处不在。对MHD湍流的基本特性的正确理解是揭示许多关键天体物理过程的先决条件。基于观察的测量技术的发展显着促进了MHD湍流理论及其对天体物理学的影响。在根据理论分析和直接数值模拟描述了对MHD湍流的现代理解之后,我们回顾了与同步加速器波动技术有关的最新发展。具体而言,我们评论了基于MHD湍流模拟和观测值的数据立方体,对同步加速器波动技术的验证以及磁性湍流的几种特性的测量性能。此外,我们建议加强对磁化和3D磁场结构的研究的研究。同时,我们还讨论了使用低频阵列(Lofar)和平方公里阵列(SKA)的大量数据立方体(SKA),讨论了测量磁场特性和了解天体物理过程的新技术的前景。
It is well-known that magnetohydrodynamic (MHD) turbulence is ubiquitous in astrophysical environments. The correct understanding of the fundamental properties of MHD turbulence is a prerequisite for revealing many key astrophysical processes. The development of observation-based measurement techniques has significantly promoted MHD turbulence theory and its implications in astrophysics. After describing the modern understanding of MHD turbulence based on theoretical analysis and direct numerical simulations, we review recent developments related to synchrotron fluctuation techniques. Specifically, we comment on the validation of synchrotron fluctuation techniques and the measurement performance of several properties of magnetic turbulence based on data cubes from MHD turbulence simulations and observations. Furthermore, we propose to strengthen the studies of the magnetization and 3D magnetic field structure's measurements of interstellar turbulence. At the same time, we also discuss the prospects of new techniques for measuring magnetic field properties and understanding astrophysical processes, using a large number of data cubes from the Low-Frequency Array (LOFAR) and the Square Kilometre Array (SKA).
