论文摘要
最近发现了扩散的TEV伽马射线排放，延伸了几个中年脉冲星的脉冲星云状，这表明能量电子/正电子对正在从脉冲星风中逃脱，并在环境星际介质中辐射。已经提出，这些扩展的排放构成了一个独特的非热来源，称为“脉冲星晕”。在本文中，我将回顾Pulsar Halos的研究进度，并讨论我们对其物理学的当前理解，包括多波长度观测，不同的理论模型，以及对宇宙射线正电子过多和银河系弥漫性γ射线发射的起源的影响。
Diffusive TeV gamma-ray emissions have been recently discovered extending beyond the pulsar wind nebulae of a few middle-aged pulsars, implying that energetic electron/positron pairs are escaping from the pulsar wind nebulae and radiating in the ambient interstellar medium. It has been suggested that these extended emissions constitute a distinct class of nonthermal sources, termed "pulsar halos". In this article, I will review the research progress on pulsar halos and discuss our current understanding on their physics, including the multiwavelength observations, different theoretical models, as well as implications for the origin of cosmic-ray positron excess and Galactic diffuse gamma-ray emission.
