2008年初甚高能gamma-ray天文学现状

Status of Very High Energy gamma-ray Astronomy as of early 2008

Arache Djannati-Atai

摘要:

利用新一代成像望远镜,特别是通过H.E.S.S.进行的银道面巡天,在甚高能伽马射线波段获得的数据,MAGIC和最近VERITAS的低阈值观测揭示了数十个银河系和河外源,提供了关于我们宇宙中各种高能加速点的丰富信息。此外,水切伦科夫仪器Milagro在经过七年的数据集成后提供了几个扩展源。这些结果的概述,重点放在一些最近的亮点。

英文摘要:

Data obtained in the very high energy gamma-ray band with the new generation of imaging telescopes, in particular through the galactic plane survey undertaken by H.E.S.S., low threshold observations with MAGIC and more recently by operation of VERITAS, have revealed dozens of galactic and extragalactic sources, providing a wealth of information on a variety of high energy acceleration sites in our universe. Also, the water Cherenkov instrument Milagro has provided several extended sources after seven years of data integration. An overview of these results with focus on some of the most recent highlights is given.
