用SHALON镜切伦科夫望远镜对壳型超新星遗迹的甚高能观测
Very Hight Energy Observationa of Shell-Type Supernova Remnants with SHALON Mirror Cherenkov Telescopes
摘要:
通过任何方法,包括镜面切伦科夫望远镜,对VHE伽马射线源的研究都涉及宇宙射线起源的问题,因此,银河系在其产生中的作用。SHALON观测获得了不同演化阶段的银河壳型超新星遗迹的结果。其中包括:Tycho的SNR,Cas A,IC 443,$γ$ Cygni SNR和经典新星GK Per(Nova 1901)。对每种信噪比,给出了SHALON的观测结果和光谱能量分布,并与其它实验数据和SHALON图像进行了比较。收集的实验数据证实了Tycho的SNR、Cas A和IC 443中关于800 GeV - 100 TeV $γ$ -射线强子产生机制的理论预言。
英文摘要:
The investigation of VHE gamma-ray sources by any methods, including mirror Cherenkov telescopes, touches on the problem of the cosmic ray origin and, accordingly, the role of the Galaxy in their generation. The SHALON observations have yielded the results on Galactic shell-type supernova remnants (SNR) on different evolution stages. Among them are: SNRs Tycho's SNR, Cas A, IC 443, $γ$Cygni SNR and classical nova GK Per (Nova 1901). For each of SNRs the observation results are presented with spectral energy distribution by SHALON in comparison with other experiment data and images by SHALON. The collected experimental data have confirmed the prediction of the theory about the hadronic generation mechanism of very high energy 800 GeV - 100 TeV $γ$-rays in Tycho's SNR, Cas A and IC443.
