伽马射线暴的X射线偏振

X-ray Polarization of Gamma-Ray Bursts

Davide Lazzati

摘要:

伽马射线暴的瞬发和余辉发射中的线性偏振的程度和时间演化是对伽马射线暴喷流及其微观和宏观物理的一些关键特征的非常可靠的诊断。本文综述了伽玛暴喷流在瞬发、闪光和余辉辐射过程中偏振辐射理论的研究现状。我将理论预测与现有的观测结果进行了比较,并从理论和观测的角度讨论了未来的前景。

英文摘要:

The degree and the temporal evolution of linear polarization in the prompt and afterglow emission of gamma-ray bursts is a very robust diagnostic of some key features of gamma-ray bursts jets and their micro and macro physics. In this contribution, I review the current status of the theory of polarized emission from GRB jets during the prompt, optical flash, and afterglow emission. I compare the theoretical predictions to the available observations and discuss the future prospect from both the theoretical and observational standpoints.
