用Milagro探测伽马射线暴的甚高能量辐射

Search for Very High Energy Emission from Gamma-Ray Bursts using Milagro

Pablo M. Saz Parkinson

摘要:

EGRET已经探测到能量为GeV的伽马射线暴,模型预测发射能量大于100 GeV。Milagro是一种宽视场(2 sr)高占空比(> 90%)地基水切伦科夫探测器,可记录能量范围为100 GeV至100 TeV的大量空气簇射。我们从2000年初以来由BATSE、BeppoSax、HETE-2、INTEGRAL、Swift或IPN探测到的106个伽马射线暴(GRB)样本中寻找了甚高能量发射。没有证据表明,从任何的爆发已经发现,我们目前从这些爆发的上限。

英文摘要:

Gamma-Ray Bursts (GRBs) have been detected at GeV energies by EGRET and models predict emission at > 100 GeV. Milagro is a wide field (2 sr) high duty cycle (> 90 %) ground based water Cherenkov detector that records extensive air showers in the energy range 100 GeV to 100 TeV. We have searched for very high energy emission from a sample of 106 gamma-ray bursts (GRB) detected since the beginning of 2000 by BATSE, BeppoSax, HETE-2, INTEGRAL, Swift or the IPN. No evidence for emission from any of the bursts has been found and we present upper limits from these bursts.
