Abstract

X-ray observations are the strong tool to study nonthermal phenomena in the universe. Detecting synchrotron X-rays is the direct evidence of accelerated electrons in the magnetic field, and thermal X-rays from the background plasma of the acceleration sites show us their physical parameters such as temperature, density, and so on. Recent X-ray observations show us the discrepancy of the standard model of Galactic cosmic ray acceleration in supernova remnants and pulsar wind nebulae, such as high acceleration efficiency, amplification of magnetic field on the shock, escape from the shock, and so on. In this paper, we will introduce how present X-ray observatories, and near-future X-ray observatories will, contribute the understanding Galactic cosmic ray acceleration beyond the standard model, together with radio, optical, and gamma-ray observations.

银河宇宙射线的观测线索——从x射线的角度
x射线观测是研究宇宙中非热现象的有力工具。探测到同步加速器x射线是磁场中加速电子的直接证据,来自加速点背景等离子体的热x射线向我们展示了它们的物理参数,如温度、密度等。最近的x射线观测表明,银河系宇宙射线在超新星残骸和脉冲星风星云中加速的标准模型存在着高加速效率、激波上磁场的放大、激波的逃逸等差异。在本文中,我们将介绍目前的x射线天文台,以及近期的x射线天文台,以及射电、光学和伽马射线观测,将如何在标准模型之外贡献对银河系宇宙射线加速的理解。
