摘要
长伽马射线暴（GRBs）被认为起源于大质量恒星的核坍缩。高红移GRBs可以探测早期宇宙的恒星形成和再电离历史，但其探测仍然罕见。本文报告了爱因斯坦探针（EP）任务上的宽视场X射线望远镜（WXT）在0.5--4 keV波段触发的一个GRB，命名为EP240315a，其明亮峰值也通过离线分析被Swift爆发警报望远镜和Konus-Wind探测到。在红移处，EP240315a在软X射线波段显示出比伽马射线波段更长且更复杂的光变曲线。得益于大视场（约3600平方度）和高灵敏度，EP-WXT通过连续探测捕获了早期的引擎活动和延长的晚期引擎活动。EP240315a的峰值X射线通量位于先前已知高红移GRBs的微弱端，其探测展示了EP通过GRBs研究早期宇宙的巨大潜力。
