我们研究弱警报的性质，当仪器检测到低于常规显著性阈值的事件时。我们利用Swift卫星启动了对这些警报样本的快速后续观测，以便对警报进行宽带分析。在15个选定的弱警报触发器（约占整个弱触发种群的4%）中，我们确认了6个grb和一个候选AGN的存在。我们已经表明，真正的高能量事件存在于整体弱警报人群中。未来对弱警报的调查可以进一步探索爆炸瞬变的低通量状态，并为未来的伽马射线任务提供方向。
We investigate the nature of WEAK alerts, when the instruments detect an event that falls below the regular significance thresholds. We have initiated rapid follow-up observations of a sample of these alerts using the Swift satellite to allow for a broadband analysis of the alerts. Out of 15 chosen WEAK alert triggers (≈ 4% of the entire WEAK trigger population) we confirm the existence of six GRBs and, additionally, one candidate AGN. We have shown that real high energy events exist within the INTEGRAL WEAK alert population. Future investigations into WEAK alerts could further explore the low fluence regime for explosive transients and give direction for future gamma-ray missions.
