费米大面积望远镜的第一年:高能宇宙的新光

The first year of the Fermi Large Area Telescope: a new light on the high-energy Universe

Luigi Tibaldo

摘要:

近一年来,费米天文台上的大面积望远镜一直在调查我们宇宙中的高能现象。我们将概述任务的状态和第一年的观测结果,重点关注高能物理界特别感兴趣的主题:探测到高能伽马射线暴,发现新的伽玛射线源群,EGRET观测到的过量GeV弥散伽玛射线发射未得到证实,更详细地说,最近测量的宇宙射线电子能谱从20 GeV到1 TeV。

英文摘要:

For almost one year the Large Area Telescope on board the Fermi observatory has been surveying high-energy phenomena in our Universe. We will present an overview of the status of the mission and of some results from the first year of observations, focusing on the topics of particular interest for the high-energy Physics community: detection of high-energy gamma-ray bursts, the discovery of new populations of gamma-ray sources, non-confirmation of the excess of diffuse GeV gamma-ray emission seen by EGRET and, in greater detail, the recent measurement of the cosmic-ray electron spectrum from 20 GeV to 1 TeV.
