天体物理物体距离遥远，大多数都具有极端的环境，现代探测器都无法在其中生存。由于我们可以获得它们发出的辐射，因此我们应该通过观察这些辐射来了解天体物理源的特性。在本报告中，我们开发了同步加速器和轫致辐射发射机制的理论框架。同步加速器发射预计会发生在脉冲星、活跃星系核、甚至木星等行星和许多其他存在等离子体与高磁场相互作用的系统中。另一方面，轫致辐射是由于两个不同的带电粒子的相互作用而发生的。我们的目标是表征这些辐射的特性，并最终通过观察确定天体物理源的特性。
Astrophysical objects are distant and most of them have extreme environments such that none of the modern day probes would survive in them. Since we have access to the radiation emitted by them, we should gain an understanding of the properties of the astrophysical source by observing these radiations. In this report we have developed a theoretical framework of synchrotron and bremsstrahlung emission mechanisms. Synchrotron emission is expected to occur in pulsars, active galactic nuclei, even planets such as Jupiter and many other systems where there is an interaction of plasma with high magnetic fields. Bremsstrahlung on the other hand occurs due to an interaction of two unlike charge particles. Our aim is to characterize the properties of these radiations and eventually determine the properties of the astrophysical source from their observation.
