对磁场作用的理解:银河系的观点

Understanding of the role of magnetic fields: Galactic perspective

A. Lazarian, S. Boldyrev, C. Forest, J. Sarff, P. Terry

摘要:

观测,理论,建模和实验室等离子体实验的结合提供了一个多方面的方法,以开发如何磁场在银河系的设置和如何这些磁场调解影响银河系等离子体的动力学,分布和组成的重要过程中产生更大的了解。下面的一个重要重点是将实验室实验与天体物理学联系起来的机会。这种方法对于银河系附近尤其引人注目,在那里,磁场的分布和特征可以比宇宙中其他地方更详细地观察到。生产实验室等离子体的能力具有无与伦比的可访问性,允许更高层次的细节进行评估和曝光。理论和建模提供了理解重要过程的基本方法,它们是连接实验验证和天文观测的桥梁。在许多情况下,利用这一方法的研究可以利用现有的实验室设施,其成本与专门空间飞行任务的测量成本相比相当小。

英文摘要:

A combination of observation, theory, modeling, and laboratory plasma experiments provides a multifaceted approach to develop a much greater understanding of how magnetic fields arise in galactic settings and how these magnetic fields mediate important processes that affect the dynamics, distribution, and composition of galactic plasmas. An important emphasis below is the opportunity to connect laboratory experiments to astrophysics. This approach is especially compelling for the galactic neighborhood, where the distribution and character of magnetic fields can be observed with greater detail than what is possible elsewhere in the universe. The ability to produce laboratory plasmas with unparalleled accessibility permits an even greater level of detail to be assessed and exposed. Theory and modeling provide fundamental ways to understand important processes, and they act as the bridge to connect experimental validation to astronomical observations. In many cases the studies that utilize this approach can make use of existing laboratory facilities, resulting in a cost that is quite small compared to the cost of measurements in dedicated space missions.
