许多伽玛射线暴（GRB）都是从无线电波段观测到的，还有一些是在非常高的能量（VHE，>100 GeV）下观测到的。高海拔水切伦科夫（HAWC）伽马射线天文台非常适合研究VHE的瞬态现象，因为它的大视场和占空比。这些功能允许搜索VHE排放，并可以探测不同的模型假设的持续时间和光谱。在本文中，我们使用HAWC在2014年12月至2020年5月期间收集的数据来搜索来自47个短GRB样本的能量范围从80到800 GeV的发射，这些样本在此期间触发了费米，斯威夫特和科纳斯卫星。该分析被优化以在每个突发的前20 s内搜索延迟和扩展的VHE发射。我们没有发现VHE排放的证据，无论是同时或延迟，相对于即时排放。上限（90%的置信水平）上的GRB通量推导出的同步辐射自康普顿前向冲击模型的约束。当假设z = 0.3时，星际密度低至10−2 cm−3的约束条件可以得到，例如GRB 170206A和GRB 181222841的最高keV注量爆发。如此低的密度使得观察主要来自快速冷却状态的VHE排放具有挑战性。
Many gamma-ray bursts (GRBs) have been observed from radio wavelengths, and a few at very high energies (VHEs, >100 GeV). The High Altitude Water Cherenkov (HAWC) gamma-ray observatory is well suited to study transient phenomena at VHEs owing to its large field of view and duty cycle. These features allow for searches of VHE emission and can probe different model assumptions of duration and spectra. In this paper, we use data collected by HAWC between 2014 December and 2020 May to search for emission in the energy range from 80 to 800 GeV coming from a sample of 47 short GRBs that triggered the Fermi, Swift, and Konus satellites during this period. This analysis is optimized to search for delayed and extended VHE emission within the first 20 s of each burst. We find no evidence of VHE emission, either simultaneous or delayed, with respect to the prompt emission. Upper limits (90% confidence level) derived on the GRB fluence are used to constrain the synchrotron self-Compton forward-shock model. Constraints for the interstellar density as low as 10−2 cm−3 are obtained when assuming z = 0.3 for bursts with the highest keV fluences such as GRB 170206A and GRB 181222841. Such a low density makes observing VHE emission mainly from the fast-cooling regime challenging.
