GRB谱参数建模
GRB spectral parameter modeling
摘要：
伽马射线暴（GRB）的火球模型预测了大量内激波的产生，这些内激波有效地加速了带电粒子，并产生了相对小尺度的随机磁场和电场。被加速的粒子由于与随机波的相互作用而在空间中扩散，因此发射出所谓的扩散同步辐射（DSR），这与它们在大尺度规则磁场中产生的标准同步辐射形成对比。在这方面的贡献，我们提出了详细的建模的GRB谱参数，这表明，在一个强的随机磁场的非微扰DSR发射机制是一致的带参数的观测分布，也与它们之间的互相关的关键结果。
英文摘要：
Fireball model of the gamma-ray bursts (GRBs) predicts generation of numerous internal shocks, which efficiently accelerate charged particles and generate relatively small-scale stochastic magnetic and electric fields. The accelerated particles diffuse in space due to interaction with the random waves and so emit so called Diffusive Synchrotron Radiation (DSR) in contrast to standard synchrotron radiation they would produce in a large-scale regular magnetic fields. In this contribution we present key results of detailed modeling of the GRB spectral parameters, which demonstrate that the non-perturbative DSR emission mechanism in a strong random magnetic field is consistent with observed distributions of the Band parameters and also with cross-correlations between them.
