用MAGIC切伦科夫望远镜观测选定的信噪比

Observation of selected SNRs with the MAGIC Cherenkov Telescope

E. Carmona, M. T. Costado, L. Font, J. Zapatero

摘要:

超新星遗迹(SNRs)被认为是银河系宇宙射线的加速点。因此,它们预计会通过强子和/或电磁场景产生甚高能(VHE)伽马射线,因此它们是地面成像大气切伦科夫望远镜(IACT)观测的天然目标。目前,已经从几个SNR中检测到VHE发射,使其成为最丰富的银河系VHE源之一。位于加那利群岛拉帕尔马的MAGIC望远镜在过去两年中一直在对几个SNR进行观测。诸如年龄、距离、无线电通量或可能的EGRET关联(即,标准匹配那些已经用于先前成功的IACT SNR检测的标准)被用于选择候选目标。在此,我们总结了过去两年的观察结果。

英文摘要:

Supernova Remnants (SNRs) are believed to be the acceleration sites of galactic cosmic rays. As such they are expected to produce Very High Energy (VHE) gamma-rays through hadronic and/or electromagnetic scenarios, hence they are natural targets for observations with ground-based Imaging Atmospheric Cherenkov Telescopes (IACTs). Currently, VHE emission has been detected from several SNRs, making them one of the most abundant types of established galactic VHE sources. The MAGIC telescope, located in the Canary island of La Palma, has been performing observations of several SNRs over the last two years. Parameters like age, distance, radio flux, or possible EGRET association (i.e., criteria matching those already used for previous successful IACT SNR detections), were used to select candidate targets. Here we summarize the results of the past two years of observations.
