摘要

磁重联的粒子加速现在被认为是银河系和星系外黑洞源磁主导区域的一个重要过程。这一过程有助于解决当前的难题，特别是与这些源中高能耀斑发射的起源有关的难题。在本文中，我们讨论了这种加速机制，并展示了最近的分析研究和注入测试粒子的多维数值SRMHD和GRMHD(特殊和广义相对论磁流体动力学)模拟，这有助于我们理解这些源的相对论射流和日冕区域的这一过程。讨论了重联加速粒子产生的高能辐射和中微子辐射。

Magnetic reconnection, Cosmic Ray Acceleration and Gamma-Ray emission around Black Holes and Relativistic Jets

Particle acceleration by magnetic reconnection is now recognized as an important process in magnetically dominated regions of galactic and extragalactic black hole sources. This process helps to solve current puzzles specially related to the origin of the very high energy flare emission in these sources. In this review, we discuss this acceleration mechanism and show recent analytical studies and multidimensional numerical SRMHD and GRMHD (special and general relativistic magnetohydrodynamical) simulations with the injection of test particles, which help us to understand this process both in relativistic jets and coronal regions of these sources. The very high energy and neutrino emission resulting from the accelerated particles by reconnection is also discussed.
