标题： Gamma-ray halos around pulsars: impact on pulsar wind physics and galactic cosmic ray transport

摘要： TeV弥散源是一类近期被发现的超高能伽马射线发射体。这些源由延伸的多TeV辐射区域组成，最初在两个已知且邻近的脉冲星——Geminga和PSR B0656+14（Monogem）周围观测到，并且可能以不同程度的信心在少数类似年龄的其他天体周围也被发现。自它们被发现以来，TeV弥散源引起了科学界很大一部分人的极大兴趣，因为它们的存在对从脉冲星物理学到宇宙射线物理以及暗物质间接探测等一系列广泛主题都可能产生影响。本文综述了人们对TeV弥散源感兴趣的几个原因以及目前的观测现状。我们讨论了提出的理论模型及其意义，并以对该现象未来研究方向的概述作为结束。 显示英文摘要

摘要： TeV haloes are a recently discovered class of very high energy gamma-ray emitters. These sources consist of extended regions of multi-TeV emission, originally observed around the two well-known and nearby pulsars, Geminga and PSR B0656+14 (Monogem), and possibly, with different degrees of confidence, around few more objects with similar age. Since their discovery, TeV haloes have raised much interest in a large part of the scientific community, for the implications their presence can have on a broad range of topics spanning from pulsar physics to cosmic ray physics and dark matter indirect searches. In this article, we review the reasons of interest for TeV haloes and the current status of observations. We discuss the proposed theoretical models and their implications, and conclude with an overlook on the prospects for better understanding this phenomenon.
