标题： Search for Short Bursts of Gamma Rays Above 100 MeV from the Crab using VERITAS and SGARFACE

摘要： 蟹状星云脉冲星的巨无线电脉冲（GRP）现象可以用大气切伦科夫望远镜在伽马射线能量上进行研究，例如 VERITAS 和连接到惠普尔 10 米望远镜的 SGARFACE 实验。尽管这些仪器通常用于 100 GeV 以上的甚高能伽马射线天文学，但它们对持续时间高达 15$\mu$秒、超过 100 MeV 的短光子爆发也具有相当的灵敏度。受到微秒级GeV爆发现象作为GRP对应物的理论预测的启发 \cite{Lyutikov2007}，我们报告了使用 VERITAS 和 SGARFACE 实验同时观测蟹状星云脉冲星以搜寻伽马射线发射的结果。 显示英文摘要

摘要： The phenomenon of giant radio pulses (GRP) from the Crab Pulsar can be studied at gamma-ray energies using atmospheric-Cherenkov telescopes such as VERITAS and the SGARFACE experiment attached to the Whipple 10 m telescope. Although these instruments are generally used for very-high-energy gamma-ray astronomy above 100 GeV, they also provide substantial sensitivity to short bursts of photons above 100 MeV lasting up to 15 $\mu$s. Motivated by the theoretical predictions for short microsecond-scale GeV bursts as counterparts to GRPs \cite{Lyutikov2007}, we report on a search for gamma-ray emission using simultaneous observations of the Crab Pulsar taken with VERITAS and the SGARFACE experiment.
