超高能Cosmic Ray观测

Ultra High-Energy Cosmic Ray Observations

Karl-Heinz Kampert

摘要:

2007年为我们提供了关于最具能量的宇宙射线起源的杰出结果:在HiRes和Auger实验的数据中观察到了GZK效应所预期的通量抑制,Pierre Auger天文台观察到了附近活动星系核位置与trans-GZK事件到达方向之间的相关性。后一个发现标志着超高能宇宙射线天文学的开始,被认为是一个重大突破,开始揭示自然界中最极端粒子的来源。本报告总结了这些观测结果,并包括该领域的其他主要进展,主要是在2007年7月在墨西哥梅里达举行的第30届国际宇宙射线会议上提出的。随着越来越多的统计数据变得可用,从当前甚至终止的实验,系统的不同实验和技术之间的差异可以详细研究,这是希望提高我们的理解实验技术及其局限性。

英文摘要:

The year 2007 has furnished us with outstanding results about the origin of the most energetic cosmic rays: a flux suppression as expected from the GZK-effect has been observed in the data of the HiRes and Auger experiments and correlations between the positions of nearby AGN and the arrival directions of trans-GZK events have been observed by the Pierre Auger Observatory. The latter finding marks the beginning of ultra high-energy cosmic ray astronomy and is considered a major breakthrough starting to shed first light onto the sources of the most extreme particles in nature. This report summarizes those observations and includes other major advances of the field, mostly presented at the 30th International Cosmic Ray Conference held in Merida, Mexico, in July 2007. With increasing statistics becoming available from current and even terminated experiments, systematic differences amongst different experiments and techniques can be studied in detail which is hoped to improve our understanding of experimental techniques and their limitations.
