成像式空气切伦科夫望远镜的费米交叉定标

Cross Calibration of Imaging Air Cherenkov Telescopes with Fermi

M. Meyer, D. Horns, H. -S. Zechlin

摘要:

一个更新的模型的同步辐射和逆康普顿发射从人口的高能电子的蟹状星云被用来重现测量的光谱能量分布从无线电到高能γ射线。通过比较预测的逆康普顿分量和最近费米测量的星云辐射,就有可能确定星云中的平均磁场,并推导出潜在的电子能量分布。模型计算,然后可以用来交叉校准费米观测与地面的空气簇射测量。由此产生的能量校准因子的推导和可用于结合广泛的能量测量费米与地面测量。

英文摘要:

An updated model for the synchrotron and inverse Compton emission from a population of high energy electrons of the Crab Nebula is used to reproduce the measured spectral energy distribution from radio to high energy gamma-rays. By comparing the predicted inverse Compton component with recent Fermi measurements of the nebula's emission, it is possible to determine the average magnetic field in the nebula and to derive the underlying electron energy distribution. The model calculation can then be used to cross calibrate the Fermi observations with ground based air shower measurements. The resulting energy calibration factors are derived and can be used for combining broad energy measurements taken with Fermi in conjunction with ground based measurements.
