伽玛暴的MAGIC望远镜观测、现状与展望
Observation of GRBs by the MAGIC Telescope, Status and Outlook
摘要:
在甚高能(VHE)区域观测伽马射线暴(GRB)将提供有关GRB外流物理条件的重要信息。MAGIC望远镜是最适合这些观测的成像大气切伦科夫望远镜(IACT)。由于其快速的重新定位时间和低能量阈值,MAGIC能够快速启动后续观测,由GCN(GCN)的警报触发,并观察GRB的即时发射和早期余辉阶段。在运行的最后两年中,MAGIC进行了几次伽马射线暴的后续观测,但是,直到现在还没有成功探测到阈值能量大于100 GeV的VHE伽马射线。在本文中,我们修改了与MAGIC伽玛暴观测的预期,从过去几年的操作经验的基础上。
英文摘要:
Observation of Gamma Ray Bursts (GRBs) in the Very High Energy (VHE) domain will provide important information on the physical conditions in GRB outflows. The MAGIC telescope is the best suited Imaging Atmospheric Cherenkov Telescope (IACT) for these observations. Thanks to its fast repositioning time and low energy threshold, MAGIC is able to start quickly the follow-up observation, triggered by an alert from the GRB Coordinates Network (GCN), and observe the prompt emission and early afterglow phase from GRBs. In the last two years of operation several GRB follow-up observations were performed by MAGIC, however, until now without successful detection of VHE gamma rays above threshold energies >100 GeV. In this paper we revise the expectations for the GRB observations with MAGIC, based on the experience from the last years of operation.
