高能等离子体辐射过程的新程序
A new code for radiation processes in high energy plasmas
摘要:
极端天体,如X射线双星、活动星系核或$γ$ -射线爆发,都含有高能等离子体,其性质还没有很好的了解。它们不仅负责我们观察到的硬X射线和$γ$射线发射,而且它们对这些物体本身的主要动力学和能量学也有很大的影响。在这里,我们提出了一个新的动力学代码,解决了粒子和光子周围紧凑的对象的演化方程。它产生的光谱将与Simbol-X的观测结果进行比较,以限制这些物体的辐射和加速过程。
英文摘要:
Extreme objects such as X-ray binaries, AGN, or $γ$-ray bursters harbor high energy plasmas whose properties are not well understood yet. Not only are they responsible of the hard X- and $γ$-ray emission we observe but also they have a strong influence on the main dynamics and energetics of these objects themselves. Here we present a new kinetic code that solves the evolution equations for particles and photons around compact objects. It produces spectra that will be compared with observations from Simbol-X to constrain the radiation and acceleration processes in these objects.
