我们在X射线和γ射线天文学协同作用的背景下，对宇宙源中相对论电子的同步辐射和逆康普顿辐射的X射线观测进行了简要回顾。特别强调的是放在超新星遗迹，脉冲星风星云和类星体的相对论喷流的情况下。通过与TeV γ射线数据的比较，讨论了同步辐射X射线成像光谱学在研究高能电子的加速和输运以及探测磁场方面的重要作用。为了展示未来X射线观测的一些前景，我们展示了下一个主要X射线天文台ASTRO-H的科学能力，这是JAXA-NASA联合使命，将于2014年发射。
We provide a concise review of X-ray observations of synchrotron and inverse Compton radiation from relativistic electrons in cosmic sources, in the context of synergies between X-ray and γ-ray astronomy. Particular emphasis is placed on the cases of supernova remnants, pulsar wind nebulae, and relativistic jets of quasars. We discuss that imaging spectroscopy of synchrotron X-ray emission plays key roles in studying acceleration and transport of high-energy electrons, as well as in probing the magnetic field through a comparison with TeV γ-ray data. To demonstrate some prospects for future X-ray observations, we showcase the scientific capabilities of the next major X-ray observatory, ASTRO-H, which is a joint JAXA-NASA mission to be launched in 2014.
