论文摘要
由于相对论的批量运动，伽马射线爆发喷气机的结构和方向在确定它们的外观方面具有基本作用。最近发现GW170817二进制中子星合并以及相关的GRB的发现增强了人们对长长和短grb中（可能是准宇宙）喷射结构（可能是准全次）喷射结构的签名的兴趣。在这篇综述中，遵循教学方法，总结了过去二十年来GRB喷射结构研究的历史，从通用射流结构的概念的成立到对塑造结构的复杂过程的当前理解，涉及涉及射流的中心发动机以及后者与祖先遗迹的相互作用的中心发动机。我们将重点放在迅速和余辉发射以及光度函数上的可观察到的射流结构的烙印上，而不是直观的推理而不是技术解释。
Due to relativistic bulk motion, the structure and orientation of gamma-ray burst jets have a fundamental role in determining how they appear. The recent discovery of the GW170817 binary neutron star merger and the associated GRB boosted the interest in the modelling and search of signatures of the presence of a (possibly quasi-universal) jet structure in long and short GRBs. In this review, following a pedagogical approach, we summarize the history of GRB jet structure research over the last two decades, from the inception of the idea of a universal jet structure to the current understanding of the complex processes that shape the structure, that involve the central engine that powers the jet and the interaction of the latter with the progenitor vestige. We put some emphasis on the observable imprints of jet structure on prompt and afterglow emission and on the luminosity function, favoring intuitive reasoning over technical explanations.
