伽马射线暴祖源

Gamma-ray burst progenitors

Andrew Levan, Paul Crowther, Richard de Grijs, Norbert Langer, Dong Xu, Sung-Chul Yoon

摘要:

我们回顾了我们目前对长持续时间和短持续时间伽马射线暴(GRB)的祖先的理解。约束可以来自多个方向,我们使用三个不同的链:i)直接观测伽玛暴及其宿主星系,ii)参数来自建模,无论是通过人口合成和直接数值模拟和iii)我们的理解似是而非的模拟祖系统在本地宇宙中观察到。从这些联合约束,我们描述了可能的路线,可以驱动大质量的恒星,以创建长GRBs,和我们的最佳估计的情况下,可以创建紧凑的对象二进制文件,最终将形成短GRBs,以及相关的长和短GRBs的速率。我们进一步讨论了如何不同的祖先可能是在黑洞引擎或毫秒磁星模型的情况下产生的GRB,以及如何中央引擎可以提供一个统一的主题之间的许多类的极其明亮的瞬态,从发光和超发光的超新星长和短的GRB。

英文摘要:

We review our current understanding of the progenitors of both long and short duration gamma-ray bursts (GRBs). Constraints can be derived from multiple directions, and we use three distinct strands; i) direct observations of GRBs and their host galaxies, ii) parameters derived from modeling, both via population synthesis and direct numerical simulation and iii) our understanding of plausible analog progenitor systems observed in the local Universe. From these joint constraints, we describe the likely routes that can drive massive stars to the creation of long GRBs, and our best estimates of the scenarios that can create compact object binaries which will ultimately form short GRBs, as well as the associated rates of both long and short GRBs. We further discuss how different the progenitors may be in the case of black hole engine or millisecond-magnetar models for the production of GRBs, and how central engines may provide a unifying theme between many classes of extremely luminous transient, from luminous and super-luminous supernovae to long and short GRBs.
