成像极高能Gamma-Ray望远镜

Imaging Very High Energy Gamma-Ray Telescopes

Heinrich J. Voelk, Konrad Bernloehr

摘要:

介绍了利用地基成像大气切伦科夫望远镜进行甚高能量(VHE:> 100 GeV)伽马射线天文学的技术,H.E.S.S.以纳米比亚的数组为例。主要讨论了大气切伦科夫技术的物理原理,强调了近十年来它的迅速发展。目前的状况说明了两个例子:光谱和形态特征的VHE伽马射线的壳型超新星遗迹连同其理论解释,和银河平面的调查结果,显示了大量的各种非热源。最后一部分是专门为正在进行的和未来的工具发展的概述。

英文摘要:

The technique of gamma-ray astronomy at very high energies (VHE: > 100 GeV) with ground-based imaging atmospheric Cherenkov telescopes is described, the H.E.S.S. array in Namibia serving as example. Mainly a discussion of the physical principles of the atmospheric Cherenkov technique is given, emphasizing its rapid development during the last decade. The present status is illustrated by two examples: the spectral and morphological characterization in VHE gamma-rays of a shell-type supernova remnant together with its theoretical interpretation, and the results of a survey of the Galactic Plane that shows a large variety of non-thermal sources. The final part is devoted to an overview of the ongoing and future instrumental developments.
