我们从极亮的伽马射线暴990123和080319 B中学到了什么?

What did we learn from the extremely bright gamma ray bursts 990123 and 080319B?

摘要:

两个最明亮的和迄今为止研究得最好的伽马射线暴(GRB),990123和080319 B,是普通的,高度准直的GRB,产生于高密度风环境中的核心坍缩超新星爆炸,从非常近轴的视角观察。逆康普顿散射(ICS)和同步辐射(SR)是伽玛暴炮弹(CB)模型中的两种主要辐射机制,它们与暴环境一起提供了一种非常简单和足够精确的描述其瞬发和余辉辐射的多波长光变曲线的方法。

英文摘要:

The two brightest and so far the best studied gamma ray bursts (GRBs), 990123 and 080319B, were ordinary, highly collimated GRBs produced in a core collapse supernova explosion within a high-density wind environment and observed from a very near-axis viewing angle. Inverse Compton scattering (ICS) and synchrotron radiation (SR), the two dominant radiation mechanisms in the cannonball (CB) model of GRBs, together with the burst environment, provide a very simple and sufficiently accurate description of the multiwavelength lightcurves of their prompt and afterglow emissions.
