MAGIC望远镜-现状和最新成果

The MAGIC Telescopes - Status and Recent Results

S. Klepser

摘要:

MAGIC望远镜是位于加那利群岛拉帕尔马的两个成像大气切伦科夫望远镜。它们提供了现有仪器中最低的能量阈值,在标准触发模式下可低至50 GeV。这使我们能够缩小卫星和地面伽马射线观测之间的能隙,以获得足够强的源。在单视场观测的头五年里,可以获得许多有趣的结果。第二台MAGIC望远镜于2009年开始运行,可以通过立体成像提高灵敏度,2010年可能已经报告了5次新的探测。我们介绍了2010年MAGIC望远镜的现状,并回顾了在单和立体模式下获得的最新结果。其中包括探测到头尾星系IC 310,这是对Mrk 501的一项新的多波长研究,这是蟹状星云脉冲星的最新光变曲线。

英文摘要:

The MAGIC telescopes are two Imaging Atmospheric Cherenkov Telescopes located on the canary island of La Palma. They provide the lowest energy threshold among existing instruments of the kind, reaching down to 50 GeV in standard trigger mode. This allows us to close the energy gap between satellite-bourne and ground-based gamma-ray observations for strong enough sources. During the first five years of monoscopic observations, many interesting results could thus be achieved. With the second MAGIC telescope, which started operation in 2009, the sensitivity could be improved by stereoscopic imaging, and 5 new detections could already be reported in 2010. We present the status of the MAGIC telescopes in 2010 and review the latest results obtained in mono- and stereoscopic mode. This includes, among others, the detection of the head-tail galaxy IC 310, a new multiwavelength study of Mrk 501, an updated lightcurve of the Crab Pulsar.
